Hey guys I'm looking for some help with my fpr. I want to jack up my fuel pressure a little but I was wondering how much I can safely do this with the stock fuel pump. Thanks for the advice.

I'm not sure on if it will provide more, but stock fp is right around 50 psi I think its usually 47 psi but it could be a lil more or less. I'm pretty sure I'm remembering correctly... If not hopefully someone else will agree or disagree.

So do I need a walbro 255lph fuel pump and a for to raise it? Or can I do it with a for alone? I thought stock fuel pressure was about 51-52psi.

OEM FPR is built into the fuel pump basket and is not adjustable

Yeah stock is 51ish, a few people said there's was 47 so just figured it was the more correct avrg. Either way its about the same though. But you'll def need aftermarket.

Okay let me try asking my question again. Will I need a better fuel pump to raise the fuel pressure or will an aftermarket fuel pressure regulator raise the pressure alone? If not how high can the stock fuel pump go?

do you have a return fuel system? if not, then no you cannot raise your fuel pressure. Nothing on the stock fuel system is adjustable.

If you have return system along with an aftermarket FPR, the stock fuel pump will go to about 80psi before it starts bypassing fuel.

why would you want more fuel pressure?the stock pump can already outflow the stock injectors at 50psi.
