Thanks for the fast replies. Well I guess I will be pulling the tank and installing the factory screw type.

Leave the valve on the tank.Put a new o ring on the screw. never open the valve more than 2 turns.I can plow and bale hay on 2 turns open.Opening it more just wears the o ring.These valves were made by Bendix, originals will be marked so.I have found that MMO will swell original o rings . A few ounces in the gas will do it.

I had a leaky shut-off valve and bought a replacement that was leaky out of the package. So I returned it, and the replacement was leaky too. They're not made well these days. So I used a plastic shut-off valve from a lawn mower---spliced into the fuel line. No leaks, but you'll need smaller hands to open and close in the tight space under the tank...

You can change it without removing the sheet metal and tank.

I've got it down to about 30 minutes but I have had lots of practice and do have the correct tools.

The first time was closer to 2 hours.
