I have an aluminum fuel tank in my 20' boat. It is 64 gallons. I removed the tank after it had been setting for 7 years. I was going to clean it out really good and get any varnish/debris out, but luckily the previous owner had used E-free gas with stabilizer. Believe it or not, the tank was very clean inside.
Anyways, before I took the tank out, the fuel gauge worked. Now, it doesn't. When I turn the key on the gauge goes to 1/4 tank, then when I turn it off it will go back to 0.
I am pretty sure that something changed when I re-installed the tank. I pulled the sender out so that I could see inside the tank, and then re-installed it.
There is a sender wire and a ground coming off of the fuel tank that also runs to the fuel gauge. But as I recall, those were the only two wires that went to the tank. Shouldn't there be a wire from tank to ground to ground the tank out???? I didn't see any other wires. Here are the two wires that I speak of (figure 4):
There is an angled piece of aluminum on the top of the tank that I could easily fasten a wire to and run it under the floor and ground to my motor. Should I do it? (Bottom of bottom picture.)
