A stand alone 3-way fuel shutoff valve ???

I have three early V4 Magna's that have wierd tank sensor/senders that cost about $50 each to replace . Any of the original Magna's has a dual tank system with the sender in the reserve tank downstream of the main tank. If the reserve tank sensor goes bad (and I have three sensors in three bikes that are each bad) you have no warning light to tell you that you are low on fuel. These early Magna bikes have an OFF/ON tank valve that appears like it might have been designed to be a three way valve with a MAIN/RESERVE/OFF capability at one time. Otherwise the on off valve might have been used in the 3-way configuration on another motorcycle that Honda made in the 70's or 80's.
Possibly on a model sold into a different market than the USA.

DOES ANY ONE OUT THERE IN THE 'WORLD' KNOW OF A HONDA THAT HAD A STAND ALONE 3 WAY FUEL VALVE? DOES ANYONE OUT THERE KNOW IF THERE IS A STAND ALONE 3-way valve from any bike available (not a petcock with a three way valve)?

Remember that the Magnas from 82-86 had stand alone shut off valves that were not the typical petcock design that sticks a hollow rod up inside the tank attached via a tank boss on the underside of the tank. Like I said, the early Magna's have a two tank system with a stand alone shut off valve. What I want is a replacement stand alone 3- way valve from a motorcycle, preferably with an attachment similar to that of the Magna on/off valve. I want to to be able to change tanks. When I run out of gas in the main tank I want to be able to switch over to the reserve tank. I need a system that is like some of the old Harley dual tank bikes. But I have not found a source for a Harley three way valve, except a $200 - $300 billet aluminum job.

Please don't direct me to a 'marine 3-way' or a 'truck 3-way' valve, they are too big and too expensive :frown:.

Thus far as close as I have come tom a reasonably priced motorcycle size 3-way stand alone fuel valve is from a '93-'98 Polaris 'Storm' Snowmobile. It costs in the low to mid $20.00 range. I have one on order to take a look at it at my local Polaris dealership (subject to a 15% restocking fee). But I don't think it will work on the Magna's fuel set up because it has a single inlet from the tank that feeds a dual outlet to feed the triple carb setup of the Polaris 800 cc motor :crazy:. Seems rediculous to a V4 rider but I guess crazy things can happen to snowmobiles in the far north, like getting water to collect and freeze the fuel line shut on one of the two carb inlets. But it seems dumb because why would it happen at the carb inlet and not the inlet to the fuel valve itself? Hey, don't look at me, I live in soCal.

Any help from an old time Magna or Sabre Vf rider would be greatly appreciated regarding this change over to a two tank system/or maybe a fix for the tank senders that seem to be non-repairable. I've been looking for a replacement valve for almost a month. If it's possible to modify a Magna on /off valve to make it into a 3-way I would like to know about that too :smile:.
