I have a fuel tank out of a 2000 Isuzu Trooper. All the tubes and penetrations rusted to nothingness.
The outside of the tank has minor surface rusting, The inside of the tank is clean and shiny, with no leaks, But the faying surfaces between the two joined halves are spread about 3/8 inch in some areas due to rusting between.
I need to do some brazing on the fuel tank, so will have the O-A set in hand,
Can heat be used to clear out the rust prior to refinishing? If the halves are resistance welded, I'm sure any heat would be tolerated. If the halves are BONDED, Heat would be the end.
Replacement fuel tanks are NOT available for these vehicles, I can't even source fuel pump assemblies to get the tubing parts.
So I'll do the repairs myself.
Don't worry all you safety first guys, The tank has been sloshed out with hot sudsy water. You can't even smell fuel with a nose to the fuel pump access hole.
If you know about fuel tanks, I'm listening.
TIA
