Fuel Shut Off Valve

'31 Patina

Senior Member
I have a '31 coupe with the shut off valve in the cab under the gas tank. Gas slowly leaks from the jam nut on the handle.

Is it best to just buy a new valve or would it be worth trying the repair kit? The repair kit comes with packing, jam nut and lock washer. Is it possible that the valve I have needs new packing and that's why it's leaking?

Thanks!
 
Before tackling the packing on the valve be sure it isn't leaking down to the carb. You could spend a lot of time fixing a bad valve. A little tooth past is a good way to lap the valve before installing the packing, just to be on the safe side. My 2¢
 
Is it difficult to repair the valve? It's not leaking down to the carb. It's only leaking around the jam nut on the handle.
 
I purchased new USA valve from Snyder's and installed it only to find out one of my gas lines inside had a small crack.
So not to play around I ordered new fuel lines and now happy and feel better that I did replace everything inside cab for I did not want to smell gas
inside cab.
I also felt the fuel lines were better designed and sealed better than the
ones that were there.
You surely do not want to have to drain that tank a lot to keep fixing
an interior leak..
 
I put in a new aftermarket valve on my 29 Huckster. But it leaked into the carb so thus the gas was not shut off. So I had to put another valve in between the one in the tank and the gas line. So it may be worth a try to repair the old.
