Hisun fuel gauge

[rtate1050 2]

I've had my Massimo 500 for about a month. So far I'm really happy with it and until today haven't had any issues . When It was delivered, the fuel gauge had one bar so I put a couple of gallons in to get me going. Still showed one bar on gauge but I figured not enough to register. Today I thought that I'd add a 5 gal can to top off. Well, I learned that the gauge wasn't working when, you guesssed it, the tank overflowed after a couple of gallons in. Still only one bar on gauge.

I could probably figure this out by starting with the basics (checking wires , the sending unit , etc. ) but before I got a-rippin and a-tearin , I thought I might save some time and I'd check and see if anyone had already had  this problem and what the fix was.  This is a 2007 with the electronic dash. Everything else seems to work . Any help would be appreciated .

Just an update . As usual, I was overthinking the problem based on what I read on the internet . Finally got around to pulling the pass. seat and found a loose wire where it goes into the plug on the pump. Pushed the wire securely into the plug and that fixed the problem. A perfect example of the  K.I.S.S principle.
