Is it possible to braze holes in a fuel tank?

Got a RH tank with a hole in it.....can't throw it out - need to repair it.

Take it to a radiator place. One in Castle Hill did Barney's. They brazed it or leaded it, then put a resin kit (from bike shop) in it.
:idea: PM Baracade he just got his 2 done. :wink:

I cleaned one up and externally fibreglassed it, lasted for years. Lead wiping would work, but fibreglass is easier and definitly non flammable. I saw some CIG guys at Amaroo Park take a damaged tank out of a car, empty and rinse it. Then they purged it with CO2 and welded the hole. I left the pits before the welding started, I just wasn't that brave.

Except for the fact you have a volatile mixture inside. Don't blow yourself up Anton! :oops:

What sort of dinero are rad places charging for this type of work :?:

I have a large tank with pinholes.....

supplementary question: if you filled a fuel tank with sand would that make it safer to weld :?:

If your tank has a rust hole it will probably get more rust holes so you need to fix the rust. Por 15 make a fuel tank repair kit. You just tip the stuff into the tank and slosh it around and it coat the inside of the tank. Problem fixed for good.
There are other brands around.

Good idea to put some gravel in there first and rumble it around, gets rid of the loose stuff.
I'd be game to weld or braze it, but only if it was hotwashed, upturned and 98% filled with water while I did it... :wink:
Then put a POR15 kit in it.

I had a diesel tank welded, he did it full! 8)

I had a petrol tank welded at Winton, we flushed it with water 3 times and filled it with exhaust fumes, the bloke lit the oxy and stuck the torch straight into the filler pipe :shock: Guess he figured if it was going to blow he would at least know when it was going to blow!

You could also fill it with dry Ice so that there wouldn't be any chance of combustion.

Good idea. You wouldn't need to fill it- a few handfuls would do- dry ice boils off free CO2 gas... 8)

Wash twice with hot soapy water (degreaser)
Leave out in the sun venting for a "couple a days"
Wash again with hot soapy water

Safe as houses.

Diesel on the other hand keeps leaching out after 5 or 6 washes :roll:
