Racetronix fuel pump

[hbomb450]

Does the new racetronix set up deed the fuel pressure of as soon as you shut it down like the new walbro do? I just put the racetronix 255 setup in my car and my rail pressure falls immediately after turn the ignition off. I pulled the actuator and checked the diaphragm it seem to be ok. Just checking before I dig any deeper.

external pumps like weldon and aeromotive 1000's dont hold pressure
intank pumps should hold pressure..
if it held before the new pump and you dont have a leak you can see or smell ( outside the tank/lines at frame /at fuel rail or at regulator) its time to drop the tank and see what got messed up
the check is in the tip of the pump outlet and its possible to overtighten the clamp and ruin the check , also possible the rubber line in tank is not tight and leaking

I just did mine and it held fine. Just did the pump, not the whole assembly.

I'm gonna replace the regulator diaphragm cause thier cheap. Guess if that doesn't do I'll have to see from thier. No external leaks and car run fine idling.
