Chevy 1999 suburban fuel pump replacement?

Answer 1

HI I WORK FOR A GM DEALERSHIP SERVICE DEPARTMENT, HOPE THIS HELPS; YOU WILL NEED TO DROP THE FUEL TANK IN ORDER TO ACCESS THE FUEL PUMP MODULE. YOU MAY HAVE TO TAKE THE DRIVESHAFT OFF, THAT WILL GIVE YOU MORE ROOM TO MANEUVER THE TANK. YOU WILL HAVE TO DROP IT DOWN A LITTLE BIT TO DISCONNECT THE ELECTRICAL CONNECTORS AND FUEL LINES ON TOP OF THE TANK. ( YOU MAY WANT TO REMOVE THE FILL NECK SCREWS (3) AT THE FUEL ACCESS DOOR, AND THE FRAME GROUND AND TAKE THE FILLER NECK WITH THE TANK) NOW, DEPENDING ON WHERE YOU OBTAIN PARTS, YOU MAY HAVE TO SPLICE IN A SUPPLIED CONNECTOR AND WIRES ( TAKE CARE TO FOLLOW INSTRUCTIONS CAREFULLY, AS THERE IS 3 OR 4 DIFFERENT DIAGRAMS.. THE RING THAT HOLDS THE FUEL PUMP IN PLACE IN THE TANK IS A SPECIAL TWIST TYPE AND YOU CAN USE A HAMMER AND A BRASS DRIFT TO TURN IT. AND DONT FORGET TO TRANSFER THE FULE LEVEL FLOAT AND SENSOR AND DOUBLE CHECK AND MAKE SURE THAT THE WIRES IN THE PUMP ARE CONNECTED BEFORE YOU PUT THE TANK BACK UP.
