Fuel Pump Misery
I'm absolutely terrified of putting my newly installed fuel pump/tank back in before verifying all is good with the new pump-sender assembly. Any who have done this job can agree that doing it twice is up there with a voluntary root canal without anesthesia. Now I'm checking the resistance on the sender but I can't get a good delta on the sender when I shift the tank upside-down. I was expecting the float rheostat to move but I'm not getting a noticeably different reading. Needless to say, I can put 5 gal in it to verify but I'm curious if others have experience on verifying the level sender.

Dave I'm right there with you man looked good when I was done, installed it and gauge no worky! pulled it back out this time I used a bore scope to look in the tank to verify there wasn't a line or wire that would catch the float and all is good this time! The lines move around according to how the hat is positioned and the little clip that hold the crossover line isn't supper secure I ended up placing a tie wrap on it as well.

You should hear the sender flopping around. Definitely take it apart and take a look. The passenger side is easy... sorry if it's the driver's side you're having trouble with since that isn't as easy.
