quick question

This is a dumb question but I always like to double check things. One of the questions sniper asks is if there is a FMU present. That was only on 96-98 mustangs right therefore I dont have one.

I beleive what they are referring to is the fmu that comes with some supercharger kits that raise the fuel pressure as boost increases.

answer no you don't have one if you are using an SVT Focus pump with your stock fuel system.

FMU's are used on return style fuel systems that doesn't have an adjustable regulator with 1:1 boost refrence. They are very hard to tune. But a simple answer is you don't have one.
