FUEL SHUT OFF VALVE P/N 6749
Be careful, I received my first valve and noticed some wrench marks on the cap. There was a gob of fuel lube in each port. This is a non lubricated valve. The handle was very hard to turn. I sent it back on Dec 15 and as of today Mar 30 have heard nothing. Spruce told me it went to the Supplier but don’t know who that is. I ordered a new valve and it works great, 5 stars. I’m out the cost of the original faulty valve so far.
This valve is an excellent replacement for the one in my antique plane. Good quality and fast shipment.

FUEL SHUT OFF VALVE P/N 6749
I found it to be very stiff and was going to use a shaft to activate it, but returned it instead. If used with direct hand activation , then probably OK.

Excellent part, Excellent Shipping time...
This is the best fuel valve for a two tank system. Low cost and reliable. OFF, TANK1, TANK2, all in 180 degrees of movement. I bought this one to replace a 30 year old one in my Varieze.
Nice smooth operation and fit exactly like the original.
Be careful this is not a selector! The handle does not point in the direction of the fuel coming in ( left is left, up is right and right+down is off). I wont be using this one.

No, this valve does not have a "both" position.
Yes, we pulled one from stock and looked at the inner valve as I turned the knob and if the center was the incoming fuel, you can direct the fuel from right, to left, then off at the center.
There is not a replacement seal available. You would have to purchase a new unit if your valve is no longer good.
The valves have female 1/4" NPT threads.
The shaft is 5/16".
Yes. It does click when the ports are lined up.
No, these do not have a "both" selection. It will be either left only, right only or off.
No there is not a labeled plate specifically available for this valve.
