Very excited. I can hardly contain myself! So I suspected the lift pump, since I could not get the push rod out to check the o-ring (would hardly budge). I hit a couple junk yards to no avail. My last stop was the trusty old German Auto repair shop. Picked up a new (old) lift pump with an original push primer. The mechanic tested it by pressing down on the roller/push rod and it would push in and spring back out. At that point, I knew mine had a problem.

I swapped out the lift pumps and primed up the system. I was still getting air bubbles. I couldn't start the car due to a completely dead battery. Wouldn't charge up enough and it would jump off my truck either. So, I was still fiddle farting around with everything. This morning I got it started and had air bubbles in the return lines from the IP and return to tank. I figured I should go ahead and change the lines at the tank (supply and return) while I was changing all the fuel lines. Well, I still had air bubbles...

I figured what the heck and took it for a test drive. She is running like a scalded dog! I mean quick! I had removed the ALDA some time back but it's never run long enough to feel the effects. Anyway, I drove around for a good 20 mins and never once a hick-up or stutter. Very happy with it.

I am just not going to worry about the air bubbles in the return lines. As long as she runs, I am happy! Thanks to everyone for the help!
