"PLEASE ENSURE YOU CLEAN AND DEFUME ANY FUEL TANK OR RELATED FUEL SYSTEM COMPONENTS BEFORE CARRYING OUT ANY REPAIRS....IF YOUR UNSURE, DONT ATTEMPT IT!
I split this tank for a few reasons.
It was Crushed underneath, the bung was weeping and their was a seam crack. Also its near impossible to find another... Ive only ever seen one tank for seperate sale, and that was years ago.
I was hoping to keep its patina, and thankfully the paint was so baked on I lost very little.
There was crazing on the lower section around the bung from a build up of stale fuel muck that had leached into the copper.
I Split the tank then panel beated back to shape hoping it wasnt going to be to brittle. For the most part it held together nicely without splitting.
lead lined the corroded area, retinned all the joints...some sections had dry joints so it was inevitable it was going to leak on the seem very soon.
Retinned the filler and reinforced, resolder both halves then reinforeced the bung with a copper washer and soldered.
Tested fine and probably stronger than new.
Just need to give the lower a final linish then re-age the copper and lead then fit her up.
Total Repair time 90 mins.
