BTW anyone know of a replacement in-line fuel pump I can purchase instead of the stock vortech unit? Preferably one that will work with the vortech FMU.

[QUOTE=istan]I believe a Walbro 255 is a Vortech FMU replacement..
The Walbro is a replacement for the stock fuel regulator. It may also serve as a replacement for the combo of FMU and Aux fuel pump depending on the engine power level and achieving appropriate and safe A/F ratio..The FMU w/o the Aux fuel pump does nothing. The FMU/Aux fuel pump allows a 8:1 fuel pressure increase during boost..

yeah run the walbro and remove the aux pump and FMU. you will not get the high *** pressure increase during boost, but the walbro flows more fuel. It's better to increase fuel flow and have a lower fuel pressure.
just make sure u have an EMS to support it
