View the video above… see the problem with the pressure dropping off so quickly… This is actually from two things: First, I’ve gotten the fuel pump issue sorted out and now all fingers point to the fuel pressure regulator.
Ok, here’s what happened with my new fuel pump and the connection…
A bit closer:
Now to prevent this from happening with the new fuel pump…
Chopped off the flange…
Cleaned up and left the layer flange on so the fuel pump tube has gripping ability.
Wham-bam! That’s it. Much better.
I ran the motor for about 5 minutes… shut it down. Now the pressure comes down extra slow.
7:18pm – Engine shut down @ 39 psi
7:34pm – Gauge reading 15psi – 16 minutes later
8:45pm – Gauge reading 6psi – 1 hour and 27 minutes later
9:02pm – Gauge reading 0psi – 1 hour and 44 minutes later
————————————-
Elapsed time: 1h 44m to reach zero.
This is absolutely much better than what it was before. It was dropping to zero in matter of seconds as shown in the video above. Now, I’m picking up an Aeromotive 13103 Fuel Pressure Regulator tomorrow from AMP Performance to further solve this pressure problem.
