gas tank issues

I was removing the tank from my truck and broke off the pet**** valve. What can I do to fix this? The amount of material left on the tank is about the same amount as the valve. Both have about an inch maybe less.

 

Was it welded on, or threaded?

 

The area could be sanded well and then fibergl***ed. (most tanks don't have a drain anyway)

 

You can use 2 part epoxy to make a repair. Most epoxy will not be effected by gasoline. You can buy it any hardware store.

Perhaps you could epoxy a new bung to the tank that you could then screw a new pet**** into. Just make sure all the metal is clean.

 

That looks like it is soldered on. Most old tanks were done that way. You can use a big soldering iron to heat it up and remove it. Then make a new piece and solder it back on.Tin the new piece well before soldering it on,you want to just melt it in place. DO NOT use any kind of flame to do this.Old time rad shops did this all the time.

 

it looks like it is threaded.

 

its not the drain, it is the the fuel line to the motor.

 

I was tempted to drill it out and tap it

 

If it was threaded, drill it out just to get most of the pipe out and use an easyout to remove the rest. If you screw up, drill it to the next larger size for a pipe thread and thread it with a pipe tap.

 

Follow Trbmaxi ideas of unsoldering a replace it in fashion

 

thanks for the insight everyone

 

Cut out the damaged section about 2" square....braze a good piece with the threads already in it to cover what you cut out....overlap about 1/2" all around...don't trust epoxy on a fuel tank...any sort of flexing and it will come off...brazing is much stronger.
