Loosen air vent (1) on the fuel filter.
Unlock the priming pump by turning plunger (2) counterclockwise. Pull the plunger up. Operate the priming pump by moving plunger (2) up and down until the fuel that is free of air bubbles flows out of air vent (1).
When the fuel flows free of air bubbles, lock the priming pump. Push the plunger inward and rotate the plunger in a clockwise motion. This motion will lock the priming pump.
Tighten air vent (1). Note: Lock the priming pump before the vent plug is tightened. The pressure in the fuel system could make locking the plunger in place difficult. Wipe away any spilled fuel.
After priming the fuel system, operate the engine at low idle for several minutes. Check the fuel system for leaks.
Close the engine hood.
