Step 1

Disconnect negative battery terminal.

Unplug fuel injectors and fuel pressure sensor (on top of driver side rail).

Step 3

Disconnect the vacuum hose that connects to the fuel pressure sensor.

NOTE

In the next step you will release the fuel pressure in the fuel rails. Be sure to extinguish any open flames and disable any spark or ignition sources, or other potential fire hazards around the work area. Keep in mind that Gasoline vapors are more flammable than gasoline itself.

Step 4

Wrap a rag around the fuel pressure sensor to avoid fuel spray and loosen the bolts that attach it to the driver side rail while holding the rag tightly. Remove the bolts and the sensor from the rail.

Step 5

Use a Spring-Lok disconnect tool to separate the fuel feed line from the driver side rail.

Step 6

Use an 8mm socket to remove the (4) fuel rail hold down bolts from the intake manifold.

NOTE

Fuel rails will have some fuel remaining in them. Use caution when removing them from the engine as the remaining fuel will spill out when moving them.

Step 7
