Where can i find a decent fuel valve strainer assembly?

My fuel shutoff leaks when I crank it down (right turn) as tight as my fingers can get it. It also leaves in the in between position. It stops leaking when it is fully open, provided i really crank on it.

It seems to be leaking around the shaft that turns the fuel on/off.

Please help me find a quality unit. I wish there was a stash of new old stock.

Thx!
 
Last one I had leak through when it was shut off turned out to just need cleaning. Some junk from the fuel tank had gotten far enough to interfere with the valve seating.
Leaking past the stem when the valve is partly open is normal behavior. The valve should always be left either completely open or completely closed.

Hi,
I guess you meant gas drips from the gas strainer.
On the original gas strainers, there is supposed to be a packing inside the nut with the hole through it, at the handle. Tighten the nut slightly and see if it stops dripping. Don't overtighten the nut, it will make the handle hard to turn. :)
 
If it's leaking through to the carb you can install an inline valve between the bowl and the carb. Here's one that I did on my 57 LoBoy. Stan

Thanks 4 suggestions!

I am thinking of eliminating the strainer valve altogether and piping directly to a petcock valve before carb. I will save the old valve 4 tractor shows. 😅

OK but in doing so you eliminate the fuel filter by deleting the glass bowl and brass screen inside it. Not a good move, in my opinion. IH designed it to work that way and it's worked for about 70 years. JMHO Stan

I've done the same thing and by replacing the packing and snugging up the nut. The packing I used was similar to this below.

This process is fairly easy, quick and cheap! I repaired several leaking sediment bowls with the PTFE material. I bought mine at Lowe's in the plumbing department. You only need to use a short length, just enough to go around the shaft once. Carefully push it down evenly into the nut with a small flat screwdriver, and then begin to tighten the nut a little at a time. You can snug it down, back it off and repeat until it is packed into the nut firmly. If you get it too tight and the shutoff won't turn, just back it off a bit.
 
Below is a listing at TM Tractor Parts for a new fuel strainer, if you want a new one. You can look at the picture.
The original strainers use a screen above the bowl gasket.

It is easier to work on the gas strainer if you move the Touch Control arms to the rear or down position before shutting off the gas.

I've successfully used dental floss for packing string, wrapped 3 or 4 turns around the shaft after unscrewing the nut from the bowl housing then tighten the nut back in place gently until the leak stops. As Jim Becker said, the OEM valve is designed to seat either fully open or fully closed. JMHO Stan
