Good job John. Channels memories of working on your Toro on the pier!

Pull that connector off of the valve and read Pin 4 to chassis. If it is a short, the wire may have rubbed somewhere between the float and the connector. Is is possible the float is stuck inside the tank, but that is another messy job - not sure if you can access that thing easily.

Okay, there's my guy. Ha! Did you find the wiring diagram online, or you just had this tidbit of useful information stored away in the solid state memory? To get to the sending unit, I would either need to drop the tank, or cut a hole through the bed to get access; I would not do the latter. I often regret the day I sold the '66. Often. And I had a real nice '68, my favorite year for a number of reasons; got rid of that, too, while in Naperville.

I looked online. My father in law has a 69 F100 that he bought new and restored a few years back. He has the dual tanks and I spent a bunch of time helping him sort out the tank transfer. Not quite as fancy as this one, but the fuel return makes it a little more complex.

Should be around 22.5 ohms empty and 145 full.
