Thanks for the response guys !! =)

The reason why i was asking was because when i did my turbo system i thought about doing that but i wasnt sure if it would work. So what i did was i bought a used 95 eclipse fuel rail which has the stock fpr mounted on it, and i ran a fuel return line to the tank.

I was just wondering how "EFFECTIVE" it is to put the FMU in the back were the stock fpr is ?? would it be absolutely the same as say having the fmu mounted in the engine bay next to the fuel rail fpr ?? the reaon i ask this is running a super long vacuum line may throw off the boost reading !
any thoughts on that ??
