How do you get to the sending unit on a 2005 27?

theres a small hatch under the seat. Should be a wire or two. Disconnect and replace, the sending units are generic, think theres only like two kinds, you can find them at amazon or anywhere. But if the issue stays, then I would hook up a flow meter.

Once the new one comes compare to the old one as the new one might have to be snipped or bent a certain way as I remember.

Thanks guys. My gauge never moved until it was down half a tank and then the need would bounce off full over waves. Once it showed half a tank it had about 15 gallons. It has quit doing ever that.

That's the norm for 99% of the Fountains. With the tank being tapered to the bottom and sitting non level, you'll never get an accurate reading as the fuel level is not on par to current capacity amount. When it's full, it reads full. When it's empty, it'll read empty. Everything between is just for chits and giggles. Run till its reads 1/2, then find a gas pump. When it reads 1/4, have your fenders hanging out

you probably have a livorsi sending unit if you have livorsi gauges. On the livorsi sending unit, there are two very small Phillips screw heads that adjust the resistance in the sending unit. One screw is for full and one is for empty. When I first got my 06, it read full unit it was about half, then as the story goes you out of gas. The problem was in the sending unit, gauge words fine. I filled my tanks, then adjusted each screw to read just to the full line. Mine were set pretty accurately in the empty mode. Now, my needle actually moves as the boat uses fuel and I think when they now read half full, I have half a tank of gas. Not sure of the shape of my tanks as I have the express cruiser, don't know if they are rectangular or angled, but seems to be reading somewhat accurately now. If adjusting the screws doesn't work, I would recommend a livorsi sending unit as it is just an aluminum tube. Doesn't move around like the one above. Good luck.
