Installing FMU

Installing FMU
I am putting together a turbo kit for my 1997 Jeep Wrangler TJ with a 2.5L 4 cyl motor. I am going to upgrade the injectors and use an FMU to run around 6-7 psi of boost. The problem is that on the Fuel rail for my Wrangler there is no fuel return line, my question is how should i install the FMU? should i just run a fuel return line to the tank? and remove the regulator and filter assembly from the tank and use an inline filter?
any help greatly appreciated.
thanks
John

Re: Installing FMU
You will have to remove the stock pressure regulator/filter and run a return line. You may have to modify the stock fuel sender assembly to eliminate that regulator. You will have to run a regular fuel filter before the fmu and tap into the sender for the return off the fmu by drilling a hole and maybe using some brass fittings and jb weld.

Or you can take out the FPR out of the fuel pump assembly and run a return line.
