how to i hook up the gas tank on a nitro r/c car?

i have an old r/c car with a TNT .12R nitro motor. i also have a fuel tank that has 2 hoses coming out of it. the only connection i have seen is on the side of the carb.

I'm new to nitro cars and i don't have any manuals or anything for it nor do i want to screw anything up.

There should be a line coming from the cap of the fuel tank and one from the bottom of the tank. The one coming from the bottom of the tank goes to the carb. The other line is a pressure line. It should go to the muffler. This line give you positive pressure from the tank to the carb.
