1G When is an AFPR required?

[LookDadNoBdyKit]

At what point is an AFPR needed? I have one right now with my current setup that came with the car, but I need to give it back to the old owner (part of our deal) He said if I want it, he will sell it to me for 70$ I have no clue how it will run on a stock FPR.

Will it make a big difference if I have it or not? Right now its set to 36psi base fp.
I am running a walbro 255

Yeah since your running a 255, keep the aftermarket AFPR

When you are running a bigger fuel pump a FPR is a nice thing to have. What kind is on the car right now?

Prior owner put one on mine with no AFPR, screwed the injectors up hardcore, running 30% over stock psi. First thing I bought when I found out... even before the new injectors. :b

Right now its set to 36psi base fp.

Any reason why it's not set to 43? Also with that Walboro an AFPR is not an option.

 

[Talesin]

Probably because stock is 36-38psi with the vac off, and that drops to 26-28 with the vac on... perfect for feeding blue-cap squirters.
