WARNING: DO NOT smoke or carry an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury.

WARNING: Fuel supply tubes will remain pressurized for long periods of time after engine shutdown. This pressure must be relieved before repairing of the fuel system has begun. Failure to follow these instructions may result in personal injury.

WARNING: Before disconnecting any fuel tube, release the fuel pressure from the fuel system.

Remove the Schrader valve cap at the end of the fuel injection supply manifold and attach the fuel pressure gauge. See Fig 1.
Position a suitable container for the fuel to drain into. Open the manual valve slowly to relieve the system pressure. This may drain fuel from the system. See Fig 2.
