External fuel pump question


Loves The Buicks
Having an issue with my external pump, would like some feedback on it. Besides the fact that it's obnoxiously loud, it never keeps pressure in the lines after the car is shut off. I have large braided lines front to back, and it won't pressurize them on the first prime. I always have to prime it 3-4 times with key to "on" position" in order to get pressure.

Is it normal for the pressure to bleed off? Or do I need to look for a new pump? This is the only car I've got with an external so I have nothing to compare it to.

external pumps dont have a check so they wont hold unless you install a check valve

you could just rewire so its on with ignition keyed on
