position.
WARNING
Drain fuel into a container and dispose of fuel in a safe manner.

lower housing assembly.

Allow all fuel to drain back into the fuel can. Install the protective dust cap on the fuel quick
disconnect.
7. Coil the fuel hose back to the fuel supply site and disconnect the fuel hose from the gravity feed
adapter. Connect the two ends of the fuel hose together to keep dirt or contaminants from

on the petroleum absorbent mat.
