jerryinga 08-06-2012 13:45:14 24.181.64.20 Report to Moderator	I am finishing up my restoration on a 1939 H and I have a fuel leak Problem #1 The 3W valve will not cut the fuel off completely It has a slow leak into the carb and also backs into the small tank. I have the nut tight and new felt packing. Problem #2 The Gland Fittings on the fuel line continue to leak at the 3W valve Very little maybe one drop every two hours but enough to mess up the new paint. Can I put some type of sealer on the face of the Gland? I have thread compound on the threads Thanks Jerrel [Reply]   [No Email]

Did that to my first all-fuel, a '42 "H" back around '78. Stops leaks and drips dead. I open the carburetor drain, catch the fuel, dump it in the tank as the engine dies, then let the drain open until the next time. Problem #2: If the glands and nuts have been strained hard and deformed over the years, I build new lines out of steel brake line and silver (or high lead solder if you have the steel really really clean)new glands on the ends, available from Roberts Carb. Long way to fix it, but it's factory new.   [Reply]  [No Email]

The best way to stop the seepage is to use a good screw in type fuel bowl which positively shuts off the fuel. The quarter turn style simply leak by. Then run the tractor out of fuel as intended. With the fuel shut off this way the three way can be tightened up so it won't leak and forget running it on the small tank. I put a little diesel fuel in mine to keep them from rusting. Good Luck!

It is a non-hardening silicone that resists gasoline. Works good to seal the bulb gasket even using the old gasket. Helps to lube & seal gas line fittings too. McMaster Carr has it.   [Reply]  [No Email]

Once I get one so it dont leak I wouldnt ever dream of turning it as I dont ever use the little tank anyway. John T   [Reply]  [No Email]
