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.

Q: Is this a left-right-both type of valve?

No, this valve does not have a "both" position.

Q: Does the three port have an off position? I am using it as a transfer selector, so I need left, right, and off. Regarding Part # 6749

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.

Q: My valve has a slight leak/drip when in the off position. Is there a serviceable seal inside? If so, do you sell that part?

There is not a replacement seal available. You would have to purchase a new unit if your valve is no longer good.

Q: What size are the fittings? Pipe Thread?

The valves have female 1/4" NPT threads.

Q: Can you tell me the shaft size of this valve? I have a similar valve with a 5/16 or .312 diameter shaft. This valve may work for us if we can confirm the diameter of the shaft.

The shaft is 5/16".

Q: Does the 4 port valve part number 6747 have an indicating click when ports are perfectly lined up?

Yes. It does click when the ports are lined up.
