With a tank in the cab the switch handle is on the floor just inside the drivers door.

Thomasm67, this is the same as my truck. Shotr bed with 2 tanks, one behing the seat. If you're asking about the electrical switch that controls the solenoid switch it's on your heater control panel. If you're asking about the solenoid switch itself, it is mounted to the underside of the cab, right below your left butt cheek when your driving. There is a pic in my gallery.

Not to stir up a hornets nest here but the main tank in my truck is behind the seat and the aux is above the spare tire. I know what my owners manual says and Mil1ion is correct but my truck has been backwards since I bought is in 1980.

Gary .... Mis-perception

The switch **** represents the tanks by when you flip the switch up the area under it OPENS up meaning to open the rear /Main tank.

It doesn't mean when you throw the switch toward the text (Main or Aux) that that tank is the one being opened up.

It is Opposite that holds true

The In Cab tank on my 1972 was the main, saddle tank was the aux. Different Body I knwo.

That was switched when Ford put the main tank above the spare tire carrier in the back betwwen frame rails. So the saddle tank is aux on these.

Sometime in 1980 Ford switched the tanks Front saddle tank is main, Rear is Aux on my 1981 according to the manual. The selector on the inside is labled Front and Rear, not Aux and Main, as well. Different body I know.

What I would do is if your fuel selector is in the Aux position, and gas is being emptied from the front, then it's safe to guess which tank that is. or vise versa. It might of depended on the factory worker at that moment.
