Fuel Pumps

[Tom95gt]

I need a 255lph fuel pump for my turbo i am going to be running.I beieve Holley makes two different kinds... one is i guess regular and the other is for forced induction. What's the difference? I guess I should go with the forced induction one? Anyone run that one?

The forced induction pump keeps volume up at pressures higher than stock (like if using an FMU).


Some info

Not sure about the Holley but most seem to prefer the Walbro GSS340 255 lph for boosted applications.

Probably meant nevermind.

You could always go the dual pump route, as well. 255lph in tank, and 255lph external, a la Vortech T-Rex.

Matt has you covered (I deleted my thoughts since they didnt really matter. NM = Nevermind).

I was just going to say that the Holley pump very well could be a Walbro anyways.

Yea i think they are the same

An additional bit of info on the 255 pumps

I've always understood that

one is high volume
and
one is high pressure
