Lower the hood.
Operate the priming pump in order to build fuel pressure. As the fuel pressure increases, the priming pump will come under load. Listen for the priming pump to come under load. Do not continue priming the fuel system after the priming pump is under load. Do not operate the pump for more than two minutes.
