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.
