Guest ambr607 Posted October 30, 2011 Share Posted October 30, 2011 While I've got the tank out and the sending unit out how do I verify it's sending the proper signal? The float and screen are fine but the gauge always shows about half a tank so I know I have a problem somewhere. I'd like to rule out the sending unit before reinstalling it and the tank.

The main harness was cut behind the backseat trim panel. Spliced the wiring, plugged in the sending unit, grounded the base where it mounts to the tank and it tested fine. Moving the float (with ignition on) produced the desired reading on the dash! Now I can remount the tank. I'm thinking my painted and coated tank won't ground through the body so I may have to run a wire from a sending unit screw to a suitable ground.
