AUTO-VENTING TYPE FUEL TANK
1. Disconnect the remote fuel line from tank. This will close the air vent and
prevent escape of fuel or vapors from tank.
2. Install tether cap over the fuel line connector stem. This will protect the
connector stem from being accidentally pushed‑in, allowing fuel or vapor
to escape.
