Quick Question. I resealed my pump and put a new fuel filter on. When initially starting, I can see small air bubbles traveling through the clear fuel line from the fuel filter to the IP. After idling for about 3 seconds, the air bubbles disappear, just fuel is flowing. After I shut off the motor, I can see a air bubble starting to form at the top of the clear hose where it connects to the fuel filter. There are no air bubbles traveling from the IP back to the filter through the clear fuel line. If I apply upward force on the clear fuel line and create a high point, I can see more air bubbles coming out of the fuel filter. The air bubble is about a nickel/quarter in size if the fuel line is left alone, but If upward pressure is applied to the hose, there is air and no fuel from the high point of the hose to the fuel filter. My car starts up fine, there are no visible leaks anywhere on the IP, the fuel filter, the fuel lines, both the hard and soft lines, and the unions on the fuel lines themselves. I just want to know if this is normal. If not, what is the culprit?
