There is another post about someone who put gas in the tank. They siphoned it out Gary. I have not looked at my fuel line to the tank, but I am sure it is rubber and that you could disconnect it up front near the engine and drain it there or if you tank is really close to being empty use the lift pump to help you. The lift pump is supposed to be self priming so if you get air in it it won't matter.
I have read somewhere that someone left the filter drain on the fuel filter housing open and then started the truck. They said fuel flowed like there was no tomorrow. You might try that also. None of the methods I have offered here are quick. Hope something I have said has been helpful.
