Fuel pressure wont hold need some help

I cant really adjust the regulator accurately as it will only run for 10 sec, 20 if im lucky. It will eventually drop to 0psi. Sorry I should have mentioned that

As far as I know its supposed to hold when key off. Mine is doing the same thing now. Wasn't before when I first swappedthe motor in. I changed regulator and no fix. Put new injectors but cant test yet. Others have had same issue and chances are its the hose in the tank between the pump and unit. Ill be checking that soon. I suggest u do too.

Yes it will run fine as is but at WOT at high rpm, motor will bog. If ur under boost, ull kill the motor. just cuz it runs doesn't mean its ok.

I installed a brand new sae 30r10 hose. as the one that came with the pump wasnt long enough. For a $27 hose (after my discount at napa) it better not be messed up.

That's what I thought. I used the clamps that came with the kit. Not saying thats ur problem as idk if thats thats mine either. Just saying its a possibility since others have stated thesame thing. Ill ber checking mine soon. If the easy checks ain't work out, just saying u might wanna look into it

Pinch the return line; now does it hold?
If not, pull the tank.
