Pingel's Electro-Flo fuel valve offers a unique feature as it will not allow the motorcycle to start unless the valve is in the On-position. The result is no more forgetting to turn the fuel on, starting the bike, and taking off only to have the bike kill because it has run out of fuel. The Electro-Flo fuel valve utilizes Pingel's "Guzzler" impressive 211 oz. (over 6 Liter!) per minute flow rate along with outstanding race-tested durability. Available with 22mm or 3/8" NPT fitting, both featuring a 5/16" (8mm) hose fitting. The Electro-Flo is made from solid billet aluminum and has a high luster polished finish.
