TEST OR INSPECTION
Ensure system air pressure is at least 85 PSI (586 kPa) during this procedure.
Valves are open when tabs or yellow paint tabs are aligned with direction of fluid flow.
Remove shield (WP 0493). Check if both tank-to-pump valves are closed.
If one or both tank-to-pump valves are open, troubleshoot Tank-To-Pump
Be careful when using high air pressure. High air pressure can blow out parts or
debris with force.
Air pressure should not exceed 50 PSI (345 kPa) during procedure. Failure to
comply may result in damage to equipment. Failure to comply may result in injury
Remove passenger side tank-to-pump check valve boot (WP 0296). While an assistant
puts 50 PSI (345 kPa) air pressure to system (WP 0044). Check if air pressure can be
heard escaping past passenger side tank-to-pump valve.
If air pressure can be heard escaping past passenger side tank-to-pump
valve, replace passenger side tank-to-pump valve (WP 0494).
