VST delete

Other than ProComp, is anyone running an OEM promax ECU with the fuel pump/regulator modification?

My VST delete is not going well. All plumbing is done, 38psi fuel pressure regulated, fuel is dumping into motor.

I think I have an o-ring issue on the fuel rail? Even without cranking the motor the pump would not build pressure over 25psi. I hooked the supply and return together to set pressure and tried again with same result. I have to crank the motor with no fuel supply and let it run all the fuel out. It won't even try to start with fuel pressure.

Update: I took the fuel rail out and found a pinched o-ring on 1 injector. That was causing fuel to run out of rail and into reed valve then into motor.

Does someone have a schematic and picture of how to do this on a 3.0 225

Damn, that's a clean set up! Can I get all of those parts from PPE?

I also had to purchase the 2-90* fittings and the gauge. Oh and the push lock hose also. I know the gauge faces backwards but without a 90* that was how it needed to sit. I only used it to set the pressure. Mike
