How long should the fuel tubing be?
For all hobbyists not involved in racing their car, the stock fuel line lengths are just fine. Fuel line length is commonly lengthened by several times the original length in order to prevent a flameout (engine dying) when the car is upside down. Racers sometimes use between 20-30cm (8 to 12 inches) of pressure line between the muffler or pipe and the fuel tank. This line must be wrapped around the fuel tank or another part of the car.
