Removal Procedure
Important: Three styles of fuel pressure regulators and fuel rails will be used
in this model year. Each regulator has a different footprint that consequently
changes the size of the receiving port on the fuel rail. The regulator retaining
clips are specific to each rail-regulator design and cannot be interchanged.
- Relieve the fuel system
pressure. Refer to
Fuel Pressure Relief
.
