inline pump with stock pump...no fuel pressure
 

I just installed my inline fuel pump & I have it running with my stock pump,
is that right?
(I now have no fuel pressure at the gauge on top of the fuel filter)

inlines located after the fuel filter
also installed the nasty 12:1 Fuc My Uncle

its a d15

Re: inline pump with stock pump...no fuel pressure
 

an inline is supposed to go before the filter

Re: inline pump with stock pump...no fuel pressure
 

It doesn't matter, but it might not register any fuel pressure between them, since it's all flow and the inline pump is more powerful than the stock pump.

so will it be ok?

not hurt my stock pump?

I just didnt wanna give any more strain on the stock 17 year old pump when running a fmu

Re: inline pump with stock pump...no fuel pressure
 

maybe you put it in backwards

Re: inline pump with stock pump...no fuel pressure
 

Iit would show too much pressure from both pumps fighting each each other.

Re: inline pump with stock pump...no fuel pressure
 

not if guage is on the fuel rail.

Re: inline pump with stock pump...no fuel pressure
 

no...its not backwards,

the bent brass end is the outlet (going to the fuel rail)
& the straight brass end is aiming at the fuel filter,

heres where I got my info:

I just wanna make sure,running 2 pumps like that,
isnt going to hurt anything,

because where I'm running a FMU,at high pressure,
the inlines going to help out alot,

I can feel the fuel after the inline pushing fuel like unreal,
but before the line,I dont feel any fuel,

the fuel pressure gauge is located on the fuel filter
it had fuel pressure before I installed the inline,

I thought about installing the fuel pressure gauge after the inline but before the fuel rail,
getting teh pressure from there,
but it still bugs me a little to know there isnt any fuel pressure coming from the stock intank pump./...

He said it was at the fuel filter.

Re: inline pump with stock pump...no fuel pressure
 

ya, you need the pressure gauge after both pumps.
not in between.
move it to the fuel rail if you can.
