Tested the sending unit seems to work OK, pulled it out tested it by hand, Can still only get it to read just under half. Where do I start. Should I believe this is the resistors on the old gauge?
Once I learn to post pictures I’ll get some on here

If the circuit is wired correctly and the grounds are good, it sounds like you have the wrong sending unit. With a full tank, a 30 ohm sending unit will read just under 1/2 tank when connected to a 90 ohm gauge.
