Fuel tank drains

[Rick Gardner]

I am currently down here in Mexico and have a leaking fuel tank drain which we cannot get to stop. I have a friend who is a USA A&P/IA down here right now who can do the repair and another friend coming down on Thrusday who could bring the part. Does anyone have the part number for the fuel tank drain for a 1976 T337G? To clarify, the part is the fuel tank drain at the wing root for sumping the tank. It may just be the O-rings but I prefer to be safe and change the entire valve. AVGAS down here is cheap, but not free! I would like to get it repaired before another flight and I have the right person here to do it, just need the right part which I can have someone bring down.
