The only way to get the sugar out of your tank is to drain the gas, remove the tank and clean it thorougly. If you don't do that you are likely to have problems with the pickup strainer getting clogged. Even more problematic; if you have or get any water in your tank, which is very common, the sugar will dissolve in the water and *could* make it's way into the carburetor. If it were mine, I'd pull the tank and clean it ASAP, then put a locking cap on the tank.
Yeah, what David said. I'm guessing this is on your Ram. Also a guess is the pump is in the tank and a returnless system. You ought to be able to drop the tank and remove the pump to siphon all the fuel out, then mop it out with a bunch of lint-free rags. be sure to be careful when reinstalling the pump and seal as you may wind up with an evap leak afterward. If you have an inline filter, replace it but bear in mind there may be another filter inside the pump itself (not including the sock.) flush the fuel lik=nes as best as you can with compressed air and carb cleaner. If you want to go all the way, it may be a good idea to pull the injectors and see if any crap got into the little filters there.
Sucks you live down in the boonies. We never have that kind of trouble here in the mountains!
