To squeeze a 4-stroke engine into some airplanes you have to move the firewall back in order to make room for your fuel tank. These short Graupner fuel tanks solve the problem. Absolutely NO wall flex that can allow fuel flow to vary under pressure. Superb Kavan quality. HLFK31C 20 oz.
Unique design allows cleaning without removing fuel lines.
Prevents pressure back flow. Install in line between tank and muffler. The pressure as well as the fuel in the tank can no longer escape through the muffler. Fits any standard fuel line. Valve is stamped with an arrow to indicate direction of flow.
