After I fill up the tank it only reads to half? It's brand new. For the first tank or so of gas it didn't really register. Any ideas?

Hi,
Was there any instructions from Autometer about recalibrating to match your sending unit? Autometer makes nice gauges, so you might check their web site or call them. It's an OHMs thing.
Good Luck!

The gas gauge is in effect an old fashioned analog ohm meter. The sending unit is the critical part that may need calibrating or may be shot!
