Fuel Pressure Regulator question

[MACHSTER 1]

Hey Tony do they make a fuel pressure regulator for the Mach? Or do they make an adjustable regulator for it? What did you do on the '02?

FP is controlled threw the computer on the returnless fuel systems. There is no "regulator" on those cars. It has a pressure sensor and it varies the voltage to the pump.

When running more than a 175 shot how do you get more fuel pressure?

I've seen several different ways, one that is popular is a Boost-a-pump. Wire it so it kicks on when you hit the bottle. The biggest problem with a nitrous system on the returnless fuel systems is the lean spike when the nitrous turns on. It drains the fuel rails quickly, and takes a sec for the pump to increase to refill them.

With the 80 shot on the 02, we simply used a very short fuel line and a long line from the nitrous solenoid. This gave the pump time to give the fuel before the nitrous hit.
