Jonsered 503828006  Tank Cap

The Fuel Cap attaches to the fuel tank to allow easy access to open and seal your fuel tank. Never operate your equipment without a properly sealed Fuel Cap as a missing or damaged cap can allow fuel to spill out, as well as allowing dirt and debris to get in. Contaminants in the fuel system create stress on the fuel filter and potentially cause damage to the carburetor, cylinder, or pistons. When replacing a Fuel Cap, find the exact one for your model as many include a unique dipstick and some are vented.
