Fuel Pump Modular Reservoir Assembly A recall bulletin 05-027 is being prepared to cover 2000-01 Chevrolet Suburban and GMC Yukon XL (excluding 2500 HD). The terminals in the 4-wire electrical connector at the top of the fuel pump assembly may experience fretting and high resistance. The bulletin explains how to install a repair kit 15824379 to the fuel pump assembly. It contains replacement electrical connectors, a replacement fuel level sensor, related hardware and instructions. Installing replacement connector components in the cover is a new procedure. The kit installation also requires replacing the fuel level sensor, which is an existing SI procedure. However, in this repair, you will re-use the float assembly, which is a new procedure. TIP: You are instructed to remove and discard the fuel pump fuse. A replacement is included in the kit. Using a new fuse is a precaution. TIP: After removing the connector, be sure the O-ring does not remain in the cover - Be sure the O-ring is properly seated on the connector and properly lubricated using the oil in the kit (fig. 6) . IMPORTANT: The O-ring may be damaged during installation if it is not properly lubricated. IMPORTANT: Be sure the connector is properly aligned with the opening in the cover, then use finger pressure to install the connector into place until the tab clicks. TIP: When removing the float arm from the old fuel level sensor, twist a small screwdriver under the float arm, which will push the arm from the retainers IMPORTANT: Be sure the sensor wires are properly routed through their retainers so they do not interfere with float arm operation. You need to cut the old 4-pin MetriPack 150 connector from the harness to prepare the vehicle harness for the new chassis electrical connector. IMPORTANT: Stagger the cuts by 1.5 inches (40 mm) so the splices will not overlap Match the wire colors and splice the new 4-pin GT 280 connector to the vehicle harness. TIP: There are two colors of splices in the kit. The blue splices are for the black and grey wires, and the red splices are for the purple and orange/black wires.
