Fuel Pressure Relief Procedure

WARNING: This page is about a different car, the 1988 Cadillac Allante and 1987 Cadillac Allante. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: ALWAYS release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
  1. Slowly remove the fuel tank cap to relieve any residual pressure in the fuel tank.
  2. Connect fuel gage J-34730-1 or equivalent, to fuel pressure connection. Wrap a shop cloth around fitting while connecting gage, 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.
