Thoughts on my gas gauge situation?

If you have another vehicle with a near full tank and it does not have one of those siphon guards in the filler neck, you could siphon the fuel from it into the truck. In the event you need to empty the truck tank to investigate, siphon the fuel back into your other vehicle. That way you won't have to cart gas from the gas station in small containers, and you will have a place to store fuel if you need to remove the truck's tank. You may need to use a small container to cart the fuel between the vehicles.
