WARNING: The noise cancelling foam component MUST be replaced if it has been exposed to engine fluids. Failure to replace the noise cancelling foam component that has been exposed to engine fluids may result in an engine fire resulting in catastrophic engine damage, and possible injury or death. WARNING: Fuel/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. WARNING: Wear safety glasses in order to avoid eye damage. CAUTION: Refer to Fuel and Evaporative Emission Hose/Pipe Connection Cleaning Caution . NOTE: High pressure fuel feed pipes are one time use only. ALWAYS install a NEW high pressure fuel feed pipe if the pipe is removed OR the fittings are loosened. Preliminary Procedures Relieve the fuel system pressure. Refer to Fuel Pressure Relief Remove Engine Rear Noise Shield. Refer to Engine Rear Noise Shield Replacement
1	Fuel Feed Intermediate Pipe Fitting (Qty: 3) CAUTION: Refer to Component Fastener Tightening Caution . Procedure Ensure ALL fittings are clean and dry prior to assembly. Lubricate the fuel feed intermediate pipe fittings with silicon free engine oil. Refer to Adhesives, Fluids, Lubricants, and Sealers Tighten the fuel feed intermediate pipe fittings in the sequence shown in the graphic. Tighten 28 N.m (21 lb ft)
