FIXED THE POS FORD: 64 ford fairlane bogs at wot. any ideas?
 

ok so check this out. we bought the car a few months ago and it ran fine. everything was good except for a small leak in the gas tank. couldn't afford a new tank for about a month so i took that tank off and "fixed" it with some gastank repair ----. that worked good enough to let us save up for a new tank. we ordered a new tank and the day after the "gas tank repair ----" fell off and my wife ran out of gas on the way home. so we put in the new gastank, new fuel pump and filter. filled it up and took it for a test drive. it runs great, but when you go wot it will bog. it doesn't bog right away, first it takes off then bogs. it feels like it's running out of gas, but the tank is full.

so here is some cliffs:
new tank, new sending unit, new pump, new fuel filter, new spark plugs, full tank of gas (10 gallons in a 16 gal tank).
car ran great
ran out of gas
replaced everything above
now bogs at wot.
bog might not be a great description, but it feels like it's running out of gas.

someone else said to check the timing, but
i didn't check the timing or anything like that cause all we did was change the stuff above

Re: 64 ford fairlane bogs at wot. any ideas?
 

Hmmmm... my guess would be the fuel pump. What are the specs on the new pump?

Re: 64 ford fairlane bogs at wot. any ideas?
 

stock oem replacement 64 fairlane fuel pump.

Re: 64 ford fairlane bogs at wot. any ideas?
 

Did you check the points, timing, and fuel pressure?
When replacing the tank did you pinch the vent line to the tank?
Does it bog every time or only after the car has been running for a few minutes?
When you bog does this happen at certian rpm?
Does it make a difference if you open the gas cap after bogging?
How does the rest of the ignition look?
Do you have old spark wires?
While looking at the points how does the cap and rotor look?
Did the coil checkout?
Any corroded ground wires from the engine to the battery?
I the battery registering above 12.6v and not below 10v? (like a bad cell)
Does this car have any upgrades to the ignition and/or fuel system?

Re: 64 ford fairlane bogs at wot. any ideas?
 

gonna go check the ignition ---- now

Re: 64 ford fairlane bogs at wot. any ideas?
 

clean you carb

Re: 64 ford fairlane bogs at wot. any ideas?
 

learn you english ;D
good idea mr. christ.
i'll do that while i'm out there.

Re: 64 ford fairlane bogs at wot. any ideas?
 

Clean the fuel bowl in the carb and check the throttle pump ( diaphram may have a pin hole it ).

Re: 64 ford fairlane bogs at wot. any ideas?
 

sounds like the bowl is running dry on WOT pull.....

Is the tank properly vented?

Re: 64 ford fairlane bogs at wot. any ideas?
 

i'm 99% sure there is no vent on this tank. there were only 2 holes in it, one to fill it up and one for a line to the pump.
i'm going out right now to check the ignition and clean the carb.

Re: 64 ford fairlane bogs at wot. any ideas?
 

did the new tank come with a new cap as well?

Old caps were vented, the new tank might be unvented, simple cap swap to test.

Re: 64 ford fairlane bogs at wot. any ideas?
 

if this bogging happened a while after fuel pump replacement did you use fuel with some ethonal?
cheap fuel pumps may have an a crapy diapharm in them and the alcohol will eat it out.
While a higher quality fuel pump with a nitrole diaphram will handle ethonal blended fuel.

Re: 64 ford fairlane bogs at wot. any ideas?
 

ok the carb is cool and the ignition ---- is good too. except for the ground going to the coil. i'm in the process of fixing that, but i wanted to check back with other stuff i found.

there is some kind of metal line going from the carb to the right side exhaust manifold, looks like it goes to the choke.
that line was not connected to the manifold. it looks like some brake line tubing.

also the cap might be a problem, the old cap that was on the car when we got it was broke so we bought a replacement locking cap from vatozone. it looks like it has some kind of venting setup, but when i take off the gas cap it relieves a ton of pressure. should i stick a rag in the tank instead of the cap and see if that fixes the problem?

92CXyD the only gas that has been in the car since we got it is chevron 87.

i'm going out right now to re connect the ground to the coil and make sure that line is in the manifold. then drive it around the block and see if that fixes it.
bone get back to me on the gas cap. i don't have an og one, just the new one i bought. would a rag in the tank let me know if it's the cap?

Re: 64 ford fairlane bogs at wot. any ideas?
 

not safe to have a rag in tank that would be like an invitation to a molatave cocktail party in your honor. ;D



just kidding


try with the cap on but lose enough to have ventilation but not fall off.

Re: 64 ford fairlane bogs at wot. any ideas?
 

I had this exact problem with a 61 falcon. When it was running at low throttle it was totally fine when it idled it was fine. when you opened it up it would start to go then cough and sputter. This was only after i did a tune up? Turned out to be the new shitty fuel filter. Change it with another cheapy and try. Check to make sure your line is not crimped anywhere or mashed with the hose clamp especially at the fuel filter inlets. Sounds stupid but it had me running in circles looking for something more complicated for 2 days.

Re: 64 ford fairlane bogs at wot. any ideas?
 

94 snatch: nothing sounds stupid at this point. the pump and filter are one piece. well kinda.
if nothing else works i'll try that. it's only $3.99 for a new one at vatozone, but i don't have a car to get there right now.

Re: 64 ford fairlane bogs at wot. any ideas?
 

if you have the cartridge type filter in the pump you can spin open the bottom of the pump and replace the filter should be a cg20 from fram.

Re: 64 ford fairlane bogs at wot. any ideas?
 

yeah it's $3.99 at vatozone, but i don't have a way to get there.

ok so i tried leaving the cap off a little
didn't fix it.

i tried fixing the wire to the coil
didn't fix it.

put the metal hose back into the exhaust manifold
didn't fix it.

only thing i can't try is the fuel filter, i'm gonna take it out and look at it though.

oh and there is a little bit of crushed fuel line between the pump and the carb, but it was there before all this so i'm not sure if that is the problem or not. i'm gonna try to fix it anyway, but i'm still looking for ideas guys.
could it be something to do with the tranny? i tried it in low and in drive and both had the problem. if i gas it in park or neutral it revs up no problem

Re: 64 ford fairlane bogs at wot. any ideas?
 

check your plugs and throw some more timing at it :y

Re: 64 ford fairlane bogs at wot. any ideas?
 

T a fuel line off the carb and run it to a cheap-o fuel pressure guage. They got inline ones for like 10 bucks at autozone that go to ~10 PSI. Just plug one end of it. See what your base pressure is at idle and see if it drops off at cruise, WOT, etc. That will tell you if the problem's fuel and if it's the carb or the system feeding it. I'm sure it had a mechanical pump before. Did you replace it with an electric? Perhaps with the diaghram POS autozone universal pump that's rated at 341 drops/hour @ 0 PSI? I'm betting this is a fuel pump problem.

Re: 64 ford fairlane bogs at wot. any ideas?
 

ford ran alot of returnless systems on carb setups.

replace the fuel filter with a clear fram filter BEFORE the pump, not after.

float could be out of adjustment?

get a brand name fuelpump, mechanical from summit

can you have it bog wot in neutral? what carb? etc

oh that line on the exh manifold is hotair choke. might want it

Re: 64 ford fairlane bogs at wot. any ideas?
 

it doesn't bog in park or neutral.
it's not an electric after market fuel pump. it's an oem replacement. not a universal pump...
still trying things, but i'm pretty damn sure it's not the pump.

Re: 64 ford fairlane bogs at wot. any ideas?
 

oem replacement is vatozone/advance auto


oem is oem

replacment is parts store



so whats the story?

Re: 64 ford fairlane bogs at wot. any ideas?
 

the pump is from vatozone, but oem replacement is not universal. it's vehicle specific.

anyway it's not the pump.
the filter inside was brand new looking.
one of my friends said something about the accelerator pump inside the carb. said that when you are not in gear it's fine, but in gear it's bogging means accelerator pump.
i'm starting to lean towards the tranny though. the trans fluid smells normal and doesn't look burnt, but it feels like the tranny is crapping out.

when i'm in park i can rev it to 5k rpms and hold it there for a few mins, but if i'm driving and gas it then it bogs. i can feel it kick down into low, but it doesn't take off. also if i drop it in low and gas it, it bogs also.
i'm gonna do a compression test tomorrow just in case something is wrong inside the engine, but how can i test the tranny?


should i jack up the car and drive with the wheels off the ground?

Re: 64 ford fairlane bogs at wot. any ideas?
 

Needs a turbo :y

Re: 64 ford fairlane bogs at wot. any ideas?
 

fixed

Re: 64 ford fairlane bogs at wot. any ideas?
 

Re: 64 ford fairlane bogs at wot. any ideas?
 

whats the carb? you still didnt answer

Re: 64 ford fairlane bogs at wot. any ideas?
 

missed that part.
the carb is a 2 bbl. i'm not sure what brand it was. it looks like a reman and it has an autolite tag on it.

Re: 64 ford fairlane bogs at wot. any ideas?
 

autolite carbs ------- blow.

save yourself the headache and get a holley 2bbl, 350cfm or 500cfm, direct bolton, better performance, easy to work on, etc etc


www.binderbulletin.org should have a carb, just ask. most of the vehicles came with holley 2bbl's on that site

Re: 64 ford fairlane bogs at wot. any ideas?
 

It's pretty obvious this is a fuel delivery problem. Depending on the carb, it has several fuel circuits, one of which is the accelerator pump. But that's not your problem. What you are describing is the tell tale signs of poor fuel delivery. Hence why I said check fuel pressure. It will cost ya 10 bucks for the guage and 5 bucks for enough fuel line to run it out behind the hood so you can watch it while driving. I'd be damned if I started wasting time ------- with other ---- and throwing parts at it before performing simple standard diagnostics. But yeah start changing more ---- and see how much money you can spend while seeing how many variables you can bring into play. And if it's the OEM carb junk that and get something better anyways AFTER fixing the problem at hand. 427 T-bird loved a nice vacuum secondary carter. :6

Re: 64 ford fairlane bogs at wot. any ideas?
 

i know they suck, but i just lost my job, can't afford a new carb.

why would fuel pressure have anything to do with it? if i'm in park and rev it to 5k rpms it's fine. i can hold it there forever and it's fine, but if i'm driving and i gas it, it falls on it's face.
again i'd love to throw a different carb on this car, but i don't have the money.

so lets say the fuel delivery is bad, how would i find out where the problem is?

Re: 64 ford fairlane bogs at wot. any ideas?
 

I had the same problem on my '82 mustang I went and bought another carb, tune-up, re-set timing, re-did all the primary power cables. I end up replacing the fuel pump and solved the problem.
I know you replace the fuel pump but I had to replace the fuel pump three times in a month before I found a good pump. Your fuel is under warrenty right?

Re: 64 ford fairlane bogs at wot. any ideas?
 

I tried to be diligent and ready every post to be sure I didn't duplicate anything, but lost interest and figured I'd better just post.

Fuel starvation could be the pump, the filter, a clogged line, etc. But starvation can also come from the float level being set too low.

If this starvation deal started only with the new parts, then something there might be at fault.

Also, on the old fords, the coil wires were connected with push on fittings, which sometimes get loose over the ages. I had one that was so loose that under acceleration, the connection would open just from the wire moving back, and then reconnct as the engine died and the wire would move forward. Behaved just like starvation.

Hope that helps,

Craig

Re: 64 ford fairlane bogs at wot. any ideas?
 

Insufficient fuel pressure is either because of a bad pump, or a restriction between the fuel tank and the carburetor where pressure is measured. Say the car ran fine and then I take a fuel line off and put a .050" restrictor in it. The car will still crank and run at idle, as there isn't enough flow gong through the restriction to cause much of a loss in pressure. But if you tried to drive the car, and then fuel supply needed increases 10 fold, that restriction is gonna cause pressure to go to zero and the engine won't run.

Like I said, check fuel pressure. This will tell you if there's a fuel supply problem. Others have said different things that could be the problem. So try rewiring the engine, replacing the carburetor, replace the transmission, adjust and ---- with everything, eat OC, and when that doesn't get it going right, check fuel pressure. If fuel pressure drops you at least have narrowed it down to the fuel system.

Re: 64 ford fairlane bogs at wot. any ideas?
 

lol
i'm gonna get a new engine for it...
j/k
i'm gonna get a pressure gauge today after i put a new fuel pump on my car (65 nova)

also my wife reminded me that we put the new fuel pump on cause it was doing this.

so it was doing this before the new pump went on.
when it started doing this i took out the fuel filter and there was major ---- in there so decided to replace the filter. when i got to the store i said ---- it lets replace the whole pump.

Re: 64 ford fairlane bogs at wot. any ideas?
 

file your points

Re: 64 ford fairlane bogs at wot. any ideas?
 

points are fine, thank you.

Re: 64 ford fairlane bogs at wot. any ideas?
 

fix the kink in the fuel line.

Re: 64 ford fairlane bogs at wot. any ideas?
 

reason is doesn't bog while not in gear is the same reason you can't build much boost in nuetral, no load on the motor.

Have you check the fuel filter AND be damn muther fovking sure to replace the rubber fuel line at same time!

That rubber fuel line is right next to the dizzy.........got marshmallows?
