If it aint broke don't fix it.

But I don't see why you couldn't run it.

It's not a static flow fuel pump is it? It would make sense if too much fuel flow is coming you could turn down the pump.

Don't quote me on any of it, I'm no fuel/spark pro.

Don't install it till you go turbo. If I remember right, it will up the pressure going into your motor. Or get an adjustable FPR and adjust your Fuel Pressure back to normal.

That's what I was talking about, see if yours is adjustable.

You can install it just fine. The FPR will return excess fuel to the tank, and (assuming the FPR is working) your pressure won't change a bit.
An adjustable FPR only lets you adjust what that pressure is set at, it has nothing to do with how much fuel is bypassed or what pump you're running.

yes, but if and only if the pump flow doesnt exceed the fuel return limit of the stock fpr, i remember the 255 flow so much that the FP will go up.

if the FP is up, then it will rise the AFR even if the injector is not changed.


so, if u want to put the pump in, it is cool, but just make sure you are running stock FP

I think it will just make your gas mileage go down..

I could be wrong.
