Thanks for the advice guys,

pulled the sending unit out,
checked good,,,0 ohm empty, 30 ohm full.

adjusted the arm to where I thought it should be, reinstalled, ...still not right.

took it back out, connected the wires (without) installing and moved the float up & down,
I noticed when moving float (full) up, gauge only registers 1/2 full.

As soon as I manually move the float to lower, the gauge begins to move down.
checked (all) wire connections.

?? Bad gauge or is this adjustable?
thanks again, Jim
