Fuel System Pressure Release

WARNING: To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system components.
CAUTION: A small amount of fuel may be released when servicing fuel lines or connections. In order to reduce the chance of personal injury, cover fuel line fittings with a shop towel before disconnecting to catch any fuel that may leak out. Place the towel in an approved container when disconnect is completed.
  1. Remove fuel pump fuse B1 in the console fuse dock to avoid possible fuel discharge if an accidental attempt is made to start the engine. See Figure and Figure .
  2. Loosen fuel filler cap to relieve tank vapor pressure.
  3. Connect fuel pressure gauge J 34730-1, or equivalent, to fuel pressure connection. Wrap a shop towel around fitting while connecting gage to avoid spillage.
  4. Install bleed hose into an approved container and open valve to bleed system pressure. Fuel connections are now safe for servicing.
  5. Drain any fuel remaining in gage into an approved container.
