Just tried some thinner material and just blew holes in it, I checked the packet the rods came in and it said for soldering. I also had a talk to a mate and he said to run sunlight soap along where you want to solder, when the soap turns brown it is hot enough. Any idea how thick the tank material is? I don't think this is going to be easy, I am also going to talk to another mate who has done this and get a bit more information.

It's on the order of 1mm thick in the bottom sections where the pinholes occur.

TIG welding would be the way to go welding this. I've used MIG on thicker plate but something as thin as that rates TIG like this.

Then there's also this, but there's no representation given for fuel resistance.

Unfortunately no one I know has a TIG, so I am trying to do it with what I've got. I do have an arc welder, if I set it on 160 might do the trick. :dunno I will keep at it until I start to develop a bald patch.
