Normal for new fuel pump to lose pressure?

[BUICKGN3]

My car has a new Racetronix fuel pump, new fpr and 60 lb injectors. When I shut the car down I notice on the fuel pressure gauge that it drops to 0 pretty quick. I can’t find an injector leaking down, that leaves new fpr or pump. Is this normal for their pumps?

Could be a problem with the short in tank hose. May have slid partly off or etc.

If its a Accufab fpr it is normal, try your old one and see if it drops.

Some cars hold pressure for weeks and some leak down fairly quickly. It doesn't matter either way. When the engine isn't running who cars what the fuel pressure is.


And to expand on the previous comment, if you have an Accufab FPR, toss that POS and get a Kiirbin unit.

Last Acufab I had, had machining debris in it, and would do that. Cleaned it, np....
