I install my new tank, new sending unit and put 5 gallons in 20 gallon tank. My gauge still reads Empty. I checked sending unit with ohms meter before installing it and it rwad like 9 to 68 empty to full. The old sending unit reads 6 to 48.
I got the gauge to jump to full one time with old sending unit once. Does tank need to be grounded? I put thin rubber pads between top of tank and trunk floor.
I tried putting a jumper across the 2 terminals on the plug at tank but gauge stayed on empty.
How should I go about trouble shooting this?
thanks
Bob
