OK, so back to you gurus for some assistance.
I replaced the gas tank in my ‘71 c10 from the behind the seat version to the bed rails kind from LMC. Now with a full tank, the (stock) gauge reads just under half. 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
