  • Can you post up the parts you used. Like your setup and would like yo do the same.


    I will get a parts list for you, but be advised that this setup will not work on stock ECU.


    This setup has no valve to keep pressure in the line when pump turns off. The stock ecu controls the fuel based on duty cycle, and it pulses the fuel pump on and off to achieve fuel flow it needs for the engine for a given load.


    On this setup, this means that fuel pressure isn't constant, and runs erratic on stock ecu. It would need to be reprogrammed to run the pump non-stop.


    On my Haltech ecu this is not a problem, but on stock ecu, guess you would need to check with Bob to see if its doable or not.


    You could jump the relay for the fuel pump into a heavy duty switch to manually turn the pump on and off as required, but that will give you a check engine saying pump relay is stuck shorted.


    I also have no idea how well that would work on a stock tune or bob's tune, I have not tested it.
