After getting my tank professionally re-sealed and reinstalled, my right tank fuel gauge on my 1996-completed RV-4 reads off-scale high regardless of fuel level.
Prior to any attempted repairs, the tank was only barely weeping fuel from a few rivets, and I asked my A&P if he would attempt the Loctite 290 & vacuum repair method; however, this introduced 2 new leaks that prevented any use of the tank.
I was able to correct one of the leaks which had developed at the fuel sender. I solved this leak by tightening the base nut on the fuel sender; however, the bolt seemed to rotate with the nut a small amount until I was able to cinch the nut down tightly. This stopped the fuel leak at that location.
My concern is that perhaps I damaged something within the fuel sender, now that I am having the fuel gauge read off-scale high at all times. Can anyone let me know if they suspect this would be the case or if there is another likely cause after the complete re-sealing? Thanks for your help.
