Re: fmu install?

disconnect your return line, run it to the FMU, and then from the FMU hook it up to the return line.

Vacuum line needs to be teed and ran to the FMU. Before it gets to the FMU you will need a one way check valve put in place

Your done

Yeah, just the return fuel line and a vac.


Note:

If you have bigger injectors and a tuning software you won't need it.

Ya , if you have bigger injectors FMU is not needed. If stock injectors a 6:1 FMU is what came with the PD kit.

It will work fine with the FMU at 6LBS PSI.
