Fuel pressure slow bleed down
#1 · May 9, 2020, 1:23 am
Should the fuel pressure hold at around 58psi after you turn key off or does it normally bleed off slowly? I cant see any fuel dripping
from any of the throttle bores as it bleeds pressure?

Yes, fuel pressure will bleed off normally almost instantly after shutting off the pump. I put a check valve in and now pressure holds pretty well for about 30 min, making for quicker restarts, so it's not that it drains in the throttle bores, but that it drains back through the pump to the tank, so if you can stop that, you can keep the pressure up.

Ditto - I installed a check valve back by my tank. Helps reduce crank time on start.
