Fuel tank repair
Seems my fuel tank has a very small leak around the threaded fitting at the base. What is the best way to repair? I am assuming something like brazing
would be best. What about the repair epoxy type stuff from super cheap etc?

I have brazed a couple up with good resalts, it would be permanent repair if done correctly.

Could take it to a radiator shop they soldered some fittings on to my bus tank. Was $30 for 3 fittings

soldering is the safest way. brazing uses a naked flame, to use this method you must purge the tank.

Where abouts did you take it? Was it on the coast?

I am guessing this is different to standard electrical solder?

simply block the filler neck up and fill the tank with water, just leave the part that needs repair out of the water. worked every time.

^^^WHS.
Solder isn't really meant for long term exposure to such a corrosive liquid so brazing is the best way to do it and how they would have done it back
in the 50-60's. Even welding can be done on a tank using the water method following a good few washes and flushes with degreaser and washing up
liquid.

Doesn't work EVERY time, trust me! Tank MUST be purged, as gordysbeetle says.
I'd rather wear a Beetle out by racing it than by polishing it!

Worked every time for me. simply filling the tank with water is actually purging it as it displaces all the flamable gas.

IMO a recipe for a trip to the hospital. This is NOT 100% fail safe. I've heard of them still exploding using this method.

Aparently there is some residual gasses/compounds that stay. Even if it's only 1 in a hundred......I wouldn't take the chance.
Use epoxy putty or POR 15 tank repair kit or get a professional to do it.

Even a washed tank can explode when welding as the heat drives fuel from the pores of the metal.
Proper preparation prior to welding a tank requires HOT pressure cleaning for a decent period of time. Like an hour or more.
Even then, danger is still there. Best to fill it with an inert gas like nitrogen.
I have heard of people hooking a hose to the tailpipe of a running car and purging the air that way.
May be okay in an emergency, but I wouldn't want to risk it myself.
I would just buy a kit from POR15 and seal the entire tank forever.
No rust, no holes. What more could you want?
