It is likely that it will not be stuck as you say since that is a tapered (pipe) thread. Drain the fuel from the tank, remove the line to the sediment bulb, then "lefty-loosey" spinning will remove the valve. Generally what causes these valves to leak is due to rust sediment from the tank scoring the brass barrel valve & seat. Be sure and flush the tank and then install the stand-pipe screen as a prevention.

Mine came out just as the man above said - I did not re use it as it was leaking into the foot area, just take it easy and no naked flame !!

Mine leaked as well, but I was able to fix it. I just took it out and sanded it down with 800 grit papaer. Then I lapped it in with light polishing compound. Was stiff and still leaked inside. At a recomendation here, I took it back out and lapped it in with white tooth paste. Operates smoothly and doesn't leak a drop.

I believe some jewelers would have a fine polishing compound called "Jeweler's rouge", that would do that job.

I would take Tom's Wesenberg's previous advice from a different thread re: this and use two wrenches opposite each other.

Hi 2,

Just in case you cannot "permantly" & "easily" stop your gas shut-off valve from leaking, not everybody is lucky enough to have an "old" shut-off valve that can be repaired.

For example:

1. After trying everything from valve grinding compound, to toothpaste, to jeweler's cloth "several" times about 10 years ago, for "temporarily" fixing an old shut-off valve, in later calling for ordering "additional" new gas shut-off valve repair parts, Mr. Rainmaker Ron, a retired wonderful & knowlegeable Model A Parts vendor related to me that he had accumulated almost a hundred (100) old gas shut-off valves at Model A parts swap meets over the years.

2. Later in spending lots of time, he tried earnestly to restore all 100 -- then tested them under water with compressed air. Out of the 100 he had, after trying to repair same, only "three (3)" did not leak & 97% of them leaked.

3. He suggested buying a "new" gas shut-off valve -- I did -- and it still does not leak.

4. Just think: Spending under $40.00, only "one time", for a "new" gas shut-off valve is cheap "one time" insurance & beats eight (8) months of living in a pup tent while your new house is being built to replace the one that burned down because of a Model A gas tank leaking gasoline.

5. Just a sincere humble opinion in trying to offer advice, save you valuable time, and brighten your day -- "without" flames.

On my 28 the shut-off has been leaking thru for some time. I removed it last week, like you I afraid of damage I might cause, but it came loose with no problem. Took the valve apart, cleaned, and lapped the plug and seat using BON-AMA cleanser, chucked the plug into my 3/8" drill and with Bon-Ama and water it done a good job cleaning the plug and seat, use a little fel-pro on the packing, no leaks and valve works fine...

I did use a little pipe dope on the threads of the valve...

Be sure you disconnect the battery before you mess with the gas line.

Willie Krash · 06-17-2013, 03:42 PM

Mine did not leak at the handle but at the gas line. I'm very lazy. I put a touch of seal- all on both sides, the cup and on the valve, let t dry and put it back together. That was last year.
If I remember right Bill W said to use grease. I can see that..

Tom Wesenberg · 06-17-2013, 11:50 PM

As Mike said, if you use 2 wrenches 180* apart you will not be pulling sideways on the fitting, and your chance of NOT breaking it are greatly improved.

I polished my valve taper on my lathe, using fine crocus cloth, then lapped it with toothpaste. 2 valves and no leaks in 18 years on one and 10 years on the other.
