Re:Walbro hp 255lph fuel pump
 

did your fuel pressure inscrease using the HP one? or are u using a adj fpr? im trying to get the one i can use without getttin a adj fpr right away..

so can the HP pump be used with stock fpr and have stock fuel pressure?

Re:Walbro hp 255lph fuel pump
 

I always ran a stock fuel pressure regulator, what are you worried about if it bumps it up to 40-45psi at your base who cares.

If you are tuning this thing with an adjustable fuel map you can change it so it runs fine.

Re:Walbro hp 255lph fuel pump
 

ok yea thats what i was wondering.. if i could control the fuel pressure w/ uberdata..


so i guess ill just go wth the hp one..


thanks for all the replys

Re:Walbro hp 255lph fuel pump
 

no you cant control fuel pressure with uberdata, just injector pulse.

Re:Walbro hp 255lph fuel pump
 

ok but the hp one will be ok right as long as i adjust in uberdata? set the injectors at 450 and fp at 52.. bc of the 10psi increase from the 255 pumps?

correct?

both pumps make the fuel pressure increase just the HP continues to flow after 60-70psi

please correct me if im wrong?

Re:Walbro hp 255lph fuel pump
 

The Walboro has been proven many times to go over 500hp.

Re:Walbro hp 255lph fuel pump
 

many times? Show some links with some 500whp cars running a 255 intank walbro with stock fuel lines.

Re:Walbro hp 255lph fuel pump
 

im not shooting for 500 whp at all so that doesnt matter./

200-220whp at most...

Re:Walbro hp 255lph fuel pump
 

You'll be perfectly fine with that Walbro then. Jeff or anyone else, I'm curious to know what kind of fuel system modifications actually need to be done when reaching high HP like that. What do they swap the stock fuel lines with etc.? Not that i'm planning to ever be able to have 500HP under my ass in a Honda, but it's just interesting to know.

Jeff I can show you tons. They are all F/I mustangs though. :-\
