How to Replace the Fuel Cap on a Weed Eater Blower

March 8, 2018
Fixing things makes sense. This article will help you make sense of replacing the fuel cap on your Weed Eater blower.

The fuel cap assembly consists of a vented cap, the O-ring seal, and a cap retainer. There are a few problems that can be caused by a faulty fuel cap. Leaking fuel can be caused by a cracked or missing O-ring (or a cracked cap). If your engine dies after several minutes of operation; and it won't restart before a (lengthy) waiting period; you might have a bad cap vent. The vent allows air back into the fuel tank as the fuel level drops. If air cannot get into the tank, a vacuum forms, and the fuel will stop flowing to the carburetor.

Let's get started.


REMOVING THE FUEL CAP   1. Remove the fuel cap.

a. Unscrew and remove the fuel cap from the fuel tank.

b. Pull the plastic lanyard out of the fuel tank. If the lanyard is cracked or broken, remove any plastic fragments from the fuel tank.



  2. Install the fuel cap.

a. Pinch the two legs of the new lanyard together and insert the lanyard through the opening in the fuel tank.

b. Thread the new fuel cap onto the fuel tank.
