RCI fuel cell sending unit / equus gauge not reading right
Some gauge / sender units go the opposite direction so you must be sure they are compatible
Also some gauges are actually "3 wire". The 3rd wire is often the case which must be grounded. These are called a 'bridge' type circuit....Like this one. This is also an example of a circuit where "full" is most resistance instead of least
