My old truck was a 88 T-6 I had 1 tank banded NEVER AGAIN!! It was corroded under they straps so they put a band at both straps looked good still leaked. Come to find out they never repaired the actual hole and fuel was getting between the tank and the band and would slowly seep at any pinhole. Than we had to move the tank back 6" so it fit in the saddlesproperly. Looked like crap! I had that tank off the truck 3 times in 2 weeks and repaired on the truck 2 more times. Thank god it was the passenger side tank and I could run without it. If you get it banded than I would epoxy it all the way around under the banding before they weld it.

 

That's cause they didn't do this: You must air pressure test it and re-weld any spots that are leaking.

To fix that problem, I stated this:When you can keep the banded areas partially hidden under the tank straps, the repair is much less noticeable.

Whoever fixed your tank did it half assed.

When done right, and pressure tested, you don't need that epoxy BS.

 

I drove a Cabover that had a crack Fuel Tank. The Boss welded it 2 times before he got it stoppewd. The Driver before me used a bar of soap to stop the leak till he got it back to the yard.
