Installed a new fuel sending unit about 2 months ago, tested it before I install it with the gauge, everything work.Last month I put gas in the tank and the gauge moved, but I had a leak in the pipe from tank to line so drained the tank and fixed it. Sunday I put about 3 gals of gas in and the gauge moved, no leaks so today I put in 5 more gal. of gas, should have about 1/2 tank of gas. But the gauge just move as if it only had the 3 gal. in it. Rocked the truck, beat on the tank but still the same. I don't want to pull the seat to remove the sending unit. HELP 53 3100 root
