The ones on the R/C nitro cars are just in the fuel line next to the carb? They just have a reserve of fuel itself.
Enjoy,

nope, nothing to do with fuel... They are to smooth out intake pulses a little... full size cars have something slightly similar on their air intakes, usually a resonator chamber built in.
They aren't mounted on the fuel line, although they connect to the engine (below or in the carb) with fuel line.
