New truck is here sooner than I expected. Full tank of gas in the old truck.
How do I get it out. It's a 2009 Silvarado. I tried to get a hose down the to the gas tank. But down about 2" the hose stops. Wonder if there is some kind of screen or something down there that keep the hose from reaching the gas. Would like to suck at least 20 gallons out about $75 at todays prices. I am sure the dealer will only have about 3-4 gallons in the new truck.

Its a ball valve or similiar valve that is commonly called a "rollover valve" and does exactly that. Most people think its to prevent a thief from syphoning out gas in your tank but its actually to prevent the gas from spilling out in case of a roll over. Most tanks, its basically a check ball that seals when upside down.
If it were me I would just drive the 09 truck until the tank is down, then start driving the new one.

If you have the tool to disconnect the fuel lines, you could jumper-wire the fuel pump relay and pump it out into cans like John D did with his wrecked F150.

Nothing is simple these days. Maybe a friend can help me with John's method.
Didn't want to drive the truck as we change on Monday and because when I backed the truck out of the garage to get a final trade value, I nicked the pass side mirror. Cost $350.

You dont even need to disconnect the wires for the pump itself. You will likely need a special release tool to disconnect a spot in the fuel system underneath.
Then jumper relay for the fuel pump under the hood instead and turn it on that way. Thats how I do it.
