you cant
You can't. There is an anti-siphon device in the filler neck.
These come with an anti-siphon device built into the tanks, as most current production trucks do.
An anti-siphon (or, anti-syphon) valve is a device that prevents liquid from returning to the line from which it came if a siphon action occurs. An anti-siphon device is frequently required on outdoor irrigation systems to prevent possibly contaminated water to be drawn back into the water supply lines if water pressure decreases in the water supply line. An anti-siphon device is not the same as a check valve. A check valve allows flow in only one direction, and requires pressure to function. An anti-siphon valve opens to the atmosphere when there is reduced or no pressure in the line.

They have an anti-siphon device, as most modern cars do. You'd have to drop the fuel tank and drain it.
You can not. There is an anti-siphon valve in the filler neck.You can not. There is an anti-siphon valve in the filler neck.
Not an answer, but a request to add 2003 Dodge Ram 2500 to the question. Dealer told me there was an anti-siphon device but didn't know how to defeat it???
You can't. There is an anti-siphon ball in the filler neck.You can't. There is an anti-siphon ball in the filler neck.
An anti-siphon trap is used to prevent reverse flow
Use a siphon hose inserted into the tank. To get the remaining fuel out or if your vehicle has an anti siphon device you will have to disconnect a fuel line and turn on the key. This will activate the fuel pump and fuel will flow from the line.
There is an anti-siphon valve in the filler neck. You can not siphon.
