What is the purpose of the bolt on bottom on fuel filter? To open to let air out?? I changed my filters and I get the air out of the system but once I let truck sit for an hour and go to start it it's not getting any fuel. I have to let it pump for a long time, or let the air out of system again. Do I need to loosen that screw bolt on fuel filter or have it tightened?
