Fuel switch direction???
Hi Muddymatt ,
I hope you are still out there . I too am having a problem with the fuel switch and from what you have said this is what I have deciphered:
bed = main on driver side under bed
door = Aux on passenger side under bed
cab = off
seat = main behind seat
If the arrow is pointing to one of these areas that is the correct fuel tank.
Is that right?
Our problem is ,we just bought this truck . It is a 1967 F250 Highboy 4x4 w/ the granny .It has been sitting for quite a while. My son gave it a tune up and an new carb,then it was running real good.Then he was messing with the fuel switch and our fuel gauge doesnt work ,so it is like a guessing game . There were two other fuel tanks in the back of the bed , and someone has taken them out. So now there are just the three. and there is no fuel coming to the carb. So I am going to see if this switch configuration will work and write it down. Do you have any other suggestions?

Might be a bit messy (get gas all over) but you could unhook all the lines (then plug them to keep them from dripping or pouring gas all over), remember what outlet goes to the motor.
Pull the switch out and then blow air into the outlet that goes to the motor then see where it comes out when you move the switch around.
Then when you hook the lines back up with follow them to the tank they belong to. This will tell you at what switch position each tank gets drawn from.
The issue with your set up is its likely going to be after market and could be different then other trucks.

Or, more simple and less messy: disconnect the line from the valve to the fuel pump at the fuel pump, remove the gas caps from the tanks and have someone with an ear at each tank listen for bubbling while you blow air into the line at each setting of the valve.

Well thanks guys . I looked under the truck to find that the switch only services two tanks . So I have that figured out . Then I took off the fuel hose coming from the fuel pump and filled it with gas, reconnected it and she started right up !

a cautionary tale about those old fuel selectors, for the benefit of future searches.
If you haven't turned that **** in a while (or maybe the truck is new to you), don't touch it - until you're ready to deal with what might happen next...
if the valve is bad, and you anger it by turning that ****, fuel will begin leaking from the assembly, with no way to stop it (a lot of fuel).
a short section of 3/8 hose and two clamps works for a quick fix to bypass the valve, but be prepared to get SOAKED with gas installing it
not the kind of thing you want happening just any old time.
