GENERAL PROCEDURES
Pressure Relief
WARNING: Do not smoke or carry lighted tobacco or open flame of any type when
working on or near any fuel- related components. Highly flammable mixtures are always present
and may be ignited, resulting in possible personal injury.
WARNING: Fuel in the fuel system remains under high pressure even when the engine is
not running. Before servicing or disconnecting any of the fuel lines or fuel system components,
the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing
personal injury or a fire hazard.
1. Remove the Schrader valve cap and install the Fuel Pressure Gauge.
2. CAUTION: Open the manual valve slowly on the Fuel Pressure Gauge.
Relieve the fuel pressure. zPlace the fuel in a suitable container.
