If you have an inexpensive fuel filter that has been marinating in old fuel for years, the paper-style element will probably come apart and travel directly to your carburetor or fuel injection. Replace the fuel filter before starting the engine. If it's a serviceable filter like this one, clean it and inspect the filter element. If you have a metal gas tank, expect that it has rusted during years of sitting. The rust will break loose from sloshing fuel and then clog the fuel filter. Check your filter regularly for awhile once you start driving the Jeep again.
