Would you like help with that, or just some information about it?

It sounds like you want a flexible hose that can be hooked to the gas pump at one car and the gas tank at the other car.  Are you trying to do this yourself, or have you bought a kit?  Is this something you can learn to do yourself?
assistant
Can you tell me how to get gas from a car?
user
I don’t know how to do that, but there are some things I could help with. What do you want to do in particular?
assistant
I am trying to get gas from one car into another. How can I do that?
user
So you want to “siphon” fuel from one car into another?
assistant
Yes!
