Yet another gas tank probelm

Are you sure its leaking from the sending unit?

The only plausable place could be like Mrmopartech said.. the seal on the lock ring.. it might be pinched from how tight you describe it, and if its not that, well maybe your flex line from sender to body line has a small hole in it!

i would wash it down with saopy water so the staines are near gone and let it dry. Once its dry try to make it happen again!
Then pin point it and let us know.. and i have never used sealers either. i replaced my whole tank at the beginning of summer! and its great. no leaks and im running a no vent gas cap! mines a 66 but i think i did hear that later models needed a vented cap... ill have to look into that!
