I did a carb. swap from tpi. It is on an 85TA. I got a Mallory 3 port fuel regulator. How do you hook it up. What kind of fitting do I need. What about the pump relay. I have a 350, Qjet, factory fuel pump and lines.

 

I put a mallory on my tbi to carb conversion, the bottom port is the return to the tank, the other one can be used for supply in, another for supply to the carb. I set my psi to 5lbs. DO NOT use teflon tape for thread sealant, use a paste you can get at ace hardwar specifically for fuel and oil.
