Help re: rising rate FPR, on a blowthrough turbo setup
I'm going to try this again. last time it got deleted for some reason, nobody told me why.
I need some help with my blowthrough carb setup. I have my stock gsl-se fuel pump wired to the engine fuse, so it comes on w/ the ignition.
The problem comes in with the fuel pressure. The carb needs very little fuel pressure, the gsl=se one puts out a lot. So, i have put in a mallory 4307M rising rate pressure regulator.
It doesnt seem that it is regulating anything, as it keeps flooding my engine when i try to start the car. Regardless of what pressure setting we put on it, it seems to put through the same pressure.
Some things i'm thinking are the problem:
1) Bad Mallory unit
2) Clogged fuel return line, forcing all fuel through (unlikely, we blew the return line through, didnt seem to be any restrictions.)
3) too much resistance on the return line, need to run to a new location.
What do you guys think?
I thank you for your help in advance

going from almost 40psi to like 5 or 10 psi is a lot. i would say get another fuel pump. it is probably the regulator, but i do not know whether it is a bad regulator or whether it just cannot reduce the pressure that much.
