Installation Procedure

CAUTION: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
CAUTION: Wrap a shop towel around the fuel pressure connection in order to reduce the risk of fire and personal injury. The towel will absorb any fuel leakage that occurs during the connection of the fuel pressure gage. Place the towel in an approved container when the connection of the fuel pressure gage is complete.
NOTE: Clean all of the following areas before performing any disconnections in order to avoid possible contamination in the system:
  • The fuel pipe connections
  • The hose connections
  • The areas surrounding the connections
  1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .
  2. Disconnect the quick connect coupling of the fuel feed hose from the fuel feed pipe of the fuel rail. Use a shop towel in order to catch any remaining fuel that may leak.
  3. Install the J 42982  between the fuel feed pipe of the fuel rail and of the fuel feed hose. See Special Tools .
