You can get the gas out fairly easy but you'll need to prep for it. The fuel port on the end of the fuel rail has a schraeder valve in it. Grab a rag and hold over the end while you press in on it. Gas will spurt but it should depressurize rather quickly. Next remove the schraeder valve with a valve stem tool like for a bicycle innertube. Then slip an appropriately sized hose (1/2" should work) over the end and clamp it tightly with a hose clamp (clear tubing from the home store is nice). Next find the black connector/white wire dangling behind the alternator. This is the fuel pump test lead. You need to put 12 volt power to this. The fuel pump will run continuously as long as you supply power. Drain your tank, watch the line for alot of bubbles, when the bubbles come, stop pumping or risk burning up the pump. Then simply remove the hose, reinstall the schraeder valve and add fresh gas to the tank. A few key cycles and it will reprime with fresh gas.
