2000 Industrial Gasser fuel shutoff

Hi,

I have a 1962 2000 Industrial Gasser 134 cu in. with the screw type fuel cutoff under the tank. It was froze, so I ordered a 311292 as an OEM replacement. It is leaking right out of the box around the valve stem threads when valve is open, although it seems to be delivering fuel OK. It seems to seal and not leak when the valve is closed. From the product reviews, these shutoff valves seem to frequently leak right out of the box. Can the threaded stem be pulled out to try and reseal it (packing? O-ring?) or is the solution just keep buying shutoff valves until I get a good one?

Thanks,

-Bob
 
I dont know if the hundred series use the same but I'm going threw the same problem with my 841. It didnt leak for 8 months, but now I have gone threw 3 more from various sources and various prices hoping to find one that didnt leak. I hope someone has a answer for you that helps but your not alone in your problem.
 
The answer is to replace the o-ring in the valve. Pry out the stop rivet, then the stem can be screwed out. Use a gasoline-compatible, wear-resistant o-ring such as nitrile, BUNA, or Viton. This problem is a recurring theme here, plenty of info in the archives.
 
Thanks Andy. That sounds like what I was after. Through a stroke of luck, I opened the valve this morning to move the tractor and no leak! I will keep an eye on it, but used it all day with no problem.
 
I'm thinking that the problem with the aftermarket fuel shut off's is an inferior O ring. I bought one a s a backup, and the first thing I did before putting it on the shelf was to pull the rivet and remove the valve shutoff and replace the o ring with a Viton one. And as long as it was apart I replaced the rivet with a screw, now it's ready to go.
