Yeah,it weeps some right at the inside seam where the strap goes--it's partly my fault for not installing it right away,I let several months pass before I got it in the truck--it did look dam good inside & out too,I painted it nice too,and was not expecting any problems...if I thought it was going to leak I wouldn't have used it..
It's not your fault,and I appreciate you giving it to me AND delivering it!--no need to apologize!..it's still in the truck and seems to not drip lately,I haven't filled it over 1/2 full though either...just my crap luck..maybe the strap tweaked the seam when I installed it?..
I have to take it back out again someday probably,the stupid diesel sending unit I transfered into it from the original tank was junk,now the fuel gauge buries at 3 o'clock...
I was able to unplug the sender wires, and plug the one that was on the passenger side tank I "deleted" into the wires, and the gauge does work,so its the sending unit that's dead for sure..I should have checked the gauge first,I could have used the original RH sending unit on the drivers side had I known that!.

..
Not sure if I'll even have the truck on the road much longer,the long list of "defects" on it keeps growing,so it may end up just being a "yard truck"...
The cab and inner fenders are getting pretty rotten,and that discourages me from fixing its many other sins that could "finish it off" in short order...now I'm dealing with tranny shifting issues thanks to a dead vacuum pump,the oil pan is still dripping due to rot, and I've been filling the crankcase with used oil,so it could decide to toss a rod or spin a bearing,so I'm not willing to spend much on it as far as money and labor now..
