This pump assembly is a high performance factory replacement unit. Key features:

• Drops directly into the factory fuel tank (NO CUTTING REQUIRED).

• Utilizes the factory jet siphon system so it operates just like GM intended.

• High flow pre-filter built into inlet of pump.

• Includes fuel level mounting bracket for factory leveling unit.

NOTE: The use of Teflon braided line with machine crimped hose ends is recommended. This eliminates the
possibility of fuel vapors permeating through the fuel line.

The following steps are typical of most installations:

1. Disconnect the negative battery cable and drain the fuel tanks.

2. Raise and support the vehicle.

3. Remove the right rear tire and wheelhouse panel.

4. Disconnect the fuel pump module harness connector.

5. Remove the crossover tube from the clamp located above the transmission. FIGURE 1-1

6. Removal of the driveline and exhaust may be necessary to remove the crossover tube. Once you have performed this

procedure, you will gain enough knowledge of the components that you may be able to do the procedure in the future
without lowering the driveline. You must slide the CPA ring aside so the collar can be turned counter clockwise.

7. Once the collar has been released pull the cross over tube straight back, DO NOT TWIST. Twisting of the tube will

damage the small transfer tubes inside.

8. Repeat steps 3-7 for the other side.

9. Disconnect the EVAP Crossover pipe quick connect fitting at the top of each tank right above the crossover tube

connections and remove from vehicle.

10. Remove the fuel tank strap mounting bolts, tank straps and drop the tanks out of the car.

11. Remove the lock ring from the passenger side tank. The unit is spring loaded and will pop up once the ring is

removed. FIGURE 1-3
