Title: 1986 Fuel Gauge not Working
Post by: 1986K20 on April 12, 2003, 09:02:00 pm

I have a 1986 K20 with dual tanks.  Left tank and sending unit are new.  When I fill either tank the gauge only goes up to about 3/8 full.  When empty it does read empty.  Any suggestions or solutions?

Mess with the tank selector switch, check all connections, check all GROUNDS!!! I've had ground problems with mine, also selector switch problems.
