Fuel Gauge Wiring 101

We're breaking down the basic wiring for your fuel gauge today. This video shows where the wires will connect coming from the fuel tank and from your power source or battery. Often a pontoon restoration project involves new gauges so we hope this helps.

Thanks for the video very helpful. I’m working on a 63C 10 pick up and I’ve got a new sending unit that I was testing before installing in the new fuel tank. I was trying to make sure that my cluster fuel gauge was still working properly.
Do you have a method to test my fuel gauge ?
The gauge has continuity, but I don’t know how to test to see if it works
thank you

What if you have duel fuel tanks and want the guage to respond as you switch from main to auxiliary?

Appears I only have one wire from the fuel tank. Any ideas?

Nah nah nah. Ign goes to ign so it’s only powered key on. The light go to nav anchor switch so it’s backlit when nav/anchor is on

The blue moving border is distracting and annoying
