Fuel System Pressure Release
WARNING:
ALWAYS release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
Basic diagnosis of fuel system should begin by checking fuel pump operation and fuel pressure.
- Slowly remove the fuel tank cap to relieve any residual pressure in the fuel tank.
- Connect fuel gauge J-34730-1 or equivalent, to fuel pressure connection. Wrap a shop cloth around fitting while connecting gauge, to collect the fuel. Then, place the cloth in an approved container.
- Install bleed hose into an approved container and open valve to bleed system pressure.
