    vac/boost lines question

    How should i run the lines for the FMU, bypass valve, and vac/boost gauge. The main instuctions say to tee the FMU to the FPR vac line. The paper that is with the FMU says to run it to the empty vac tree.

    Can I hook the bypass valve vac line and vac/boost gauge line to that FMU line?

    I'm running a NOVI1000 and i plumbed my FMU into the vac tree. I also plumbed my vac/boost guage into the vac tree as well. Everything works great! :teeth:

    Guess I'll just run the line from the FMU to the vac tree and tee off that for the bypass and gauge.

    Thanks
