I cant really give you a good answer because I dont know.

But i've been running a walbro 255lph with stock fuel rail and fpr on my car for almost 3 years without problems.

Im also running 550cc injectors.

I dont know if its luck or if I should get a fpr too.

You'll be fine. Whats the setup gonna be? Pretty conservative, 6-7lbs?

you really dont need a fpr until you start to see pressure drop mostly in higher horserpower car that need a 1:1 rising pressure
correct if im wrong anybody
