Fueling issue

[Tomhodgkinson]

Gday, I have a 2015 vlx wakesetter that was not in use for a period of about 12 months or so. Had a quarter tank of fuel in it. Took to petrol station and tried fuelling. Pump would stop and tried more and fuel would overflow, so I thought it was full. Got out on the water and gauge still said 1/4 tank so thought it was sticking. Not the case. Long story short the tank is now empty and cannot get fuel in. Tired to trickle fuel in and shake boat at same time and got about $40 in and gauge is still reading 0%. What might be my issue

Before you rush off and buy a new fuel sender, find it on top of the fuel tank and clean the connections.  It should have a sense wire and a ground wire that both need to be clean.  The other end of the ground wire probably terminates on a stud on one of the engine heads.  Clean those stud connections as well (both heads).

Next, get on your back under the dash and clean every connection you can find.  You should find several buss bars, switch terminations, and pigtail connectors.  Get them all clean.  If the fuel gauge still doesn't work, come back for more info.  You may discover that you have fixed other things by cleaning connectors under the dash.

As for putting fuel in, you may have a plugged vent line.  Mud Daubers like to seal the vent hole if they can, or maybe the hose is kinked or has some other blockage.  If you aren't afraid to try, you can lip lock the filler port and blow air into the tank with your lungs.  The vent should keep you from pressurizing the tank, and you will hear the air escaping through it.  If you can pressurize the tank, something is wrong.  You could use an air compressor, but the tank is only proof tested to about 3 PSI or so.
