Are you talkin about an FMU?....Fuel Management Unit?...

An FMU will only add extra fuel pressure when there is boost...So, NA you'll be fine...

no, its an aeromotive "boost reference fuel pressure regulator"
i dont know the part number though. but i can describe it to you if you want. haha

I have the same regulator on my El Camino. It will work fine N/A since it only adds fuel when it sees boost.

Should work fine. Your only adding in fuel pressure during boost so as long as the regulator is set at 40 psi thats all you'll need. This regulator must work like an FMU I would guess? I've never seen one. It's made to function either with or without boost so I wouldn't worry. Thats a new cool item to me. Never knew they made a regulator that adjusted for boost. It must be a smaller amount of pressure than an FMU. If you got a part # i'd like to check it out

most of the regulators like this add a 1 to 1 ratio meaning they will bump FP 1 psi for every pound of boost. Usualy used on bigger injector setups not using a FMU

Exactly. Not only that the Aeromotive one is a BYPASS regulator not a return style. Meaning basically that fuel is bypassed at the regulator rather than going through the system and then returned. The boost closes the bypass valve therefore adding fuel pressure. There are 2 springs available with the regulator. One that is for carbed engines 3-20 psi and one for fuel injection 21-70 psi.

what he said just make sure you run the correct size return line
