Ok so I made a template using my old tank and marked the positions of the filler neck and the air breather pipe. Then I compared it to the new tank. It was like an inch too high and 1 1/2 inches too far forward toward the front of the truck.

I did that with the tanks out. Then I took a floor jack handle and stuck it down the filler neck and slowly applied pressure in the needed direction a few times. while doing this I also stuck a phillips head screw driver in the breather hole and bend that as needed to keep it aligned. I got the filler neck to be possitioned to behind the tank half seam again but I still needed it to go down more toward the floor. A few more slow bends and it lined up pretty perfectly.

Some of the paint around the neck chipped off (I had painted it with Tank Tone from Eastwood). But I did not see any damage resulting from bending it back. No tears.

As mentioned before there was a small pinhole at the bottom of the tank and it would leak air if I pressurzed with my mouth on the breather pipe and held the filler pipe closed with my hand and held my hand over the sending mount holes.

Well the really strange thing is now with it bent back to the correct location where everything lines up, the pin hole has stopped leaking!

I am not sure I understand that. It maybe got the metal close enough by bending it back that there is no longer a hole?

I pressurized it with my mouth again and held it for a 60 seconds and there was no hissing and when I released all the air came back out.


Well I guess to be safe I will take it to a radiator shop or somewhere and see if they can pressure test it and re-sweat it if needed.

I also tried seeing how it sits in the truck and everything lines up good. And with the pads under it it is pretty snug. Without the pads it teaters a bit as the tank is a bit bend over one of the pad areas causing it to teater. But with the pads it seems to be fine.

I guess I can use this tank. I just should get it pressure tested or something.
