I checked the filter in my fuel pump and noticed it was mounted upside down. I believe the filter and lid are supposed to be on the bottom. I would have to reroute the fuels a bit to flip it over. Does it matter? The other thing I noticed is the pump is running faster than before. Before I fooled with it, it was pumping slow except when the bleed screw was pushing out air. The other thing is the ground wire seems flaky the way it is not attached to the pump except when you mount it. I reattached the ground when I remounted and made sure it was tight. Motor is running great. Do you think I have air in the pump? I did not blled at the spin on filter only at the injector pump.
