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.

  1. Slowly remove the fuel tank cap to relieve any residual pressure in the fuel tank.
  2. 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.
  3. Install bleed hose into an approved container and open valve to bleed system pressure.
