Removal and Installation
WARNING:
-
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly
flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
-
Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental
spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this
instruction may result in serious personal injury.
CAUTION: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute
cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or tubes.
1. Remove the fuel rail.
2. CAUTION: Use O-ring seals that are made of special fuel-resistant material. Use of ordinary O-rings can cause the fuel system to leak.
NOTE: Lubricate the new O-ring seals with clean engine oil prior to installation.
Remove the fuel injectors from the intake manifold and discard the upper and lower fuel injector O-ring seals.
3. To install, reverse the removal procedure.
