Are you sure it's fuel?

Even if the needles were hanging open... I don't think it would continue to draw fuel since the fuel system is a loop. It wouldn't be able to draw a siphon.

OK... I don't normally recommend thins... but use some starter fluid to help clear what ever is in the engine.

I think that one beep is low voltage. It sounds like your battery is weak. Is it a new battery. If it sat for three years you need a new battery. Take the battery out and have it tested. These things like fully charged batteries to start. Also, if you want to recharge the battery, make sure the battery switch is in the OFF position. Otherwise, you will damage the MEPM.

Got it started it was just really loaded with gas It has a brand new battery and I also put it on charger for good measure before trying to use it. Still not sure how this gas could get in here. I checked the vent that goes to the outside just under rub rail seems to be working that is the only thing I could tell that would allow the pressure from gas tank to escape. any ideas anyone thanks.
