@oldman I ran a temporary wire from the sender unit to the fuel gauge in the most direct path in a SC ute. I tried testing the omhs first with no success with getting my knowledge of multimeters to work for me Before I disconnected the wire, the gauge read just below 1/2 on the gauge. When the wire was bypassed with new wire the gauge read just below full mark, with about 50km used out of a full tank. I will be leaving the temporary wire to see how it all reads before doing a permeant fix. Think this has solved this issue. Thanks again.
