I have 2005 19ft cc polar dynasty offshore boat. Fuel gauge is stuck on full.
Should I take sending unit out of the tank to see if maybe it's gumed up or maybe need to replace? Any info would really be appreciated.
...or the sending unit's wire to the gauge has grounded along the way !!!
So, if this is the case, disconnect the wire at the gauge. If the gauge remains at full, yep, bad gauge. If it returns to empty...start tracing the wire.
