on an H22a1 what side do I splice the fmu on to the fuel rail??? I dont want to hook that thing up wrong.

On the FMU, there are 3 ports.

Top port is vacuum sources [hook this up to any vacuum source]
Side port is inlet port [ hook this port to the ORIGINAL return port from the stock FPR]
Bottom port is return port [ put the stock hose that you took out from the stock FPR to this port ]

you're basically bypassing the fuel retunr from the stock FPR to the FMU first, then back to the fuel return

naw what I mean...... the fuel rail, which fuel line to I cut to splice in the fmu and fuel pump?


theres fuel line on the throttlebody side and theres the fuel pressure regulator side. which one do I go to.


thanks

fuel pump goes in between fuel filter and fuel rail, FMU goes between FPR and the tank

ok I have everything on the right side now, but when I take it into boost at basically hits revlimiter, and leans out thats at 0psi, I am thinking I may have the fmu backwards. ok the fuel neck goes into the in on the fmu, and the out goes to the tank. is that right?
