Hi Scotty, looks like you're a fisherman too, living or pleasure? Airbag light fault is usually down to the wiring under the seat(s) and can mostly be re-set with a tool available on eBay for a few $. Fuel gauge not a real common issue but with checking the fuses and wiring on the sender, accessed behind the seats. Welcome to the forum from me near Kissimmee Fla. till next month anyway.
Tony.
