WELL IT'S NOT HARD TO REPLACE YOUR FUEL PUMP. SAFETY FIRST DISCONNECT YOUR BATTERY TERMINALS AND OR IF YOU CAN GET A FIRE EXTINGUISHER CLOSE BY BECAUSE DEALING WITH GASOLINE IT IS VERY FLAMMABLE. YOU WOULD NEED A 5/8" OPEN END WRENCH, A FLAT TIP SCREW DRIVER NO#2, 3/8 DRIVE 1/2" SOCKET WITH RACHET, A DRAIN PAN TO CATCH FUEL FROM THE MAIN LINE WHEN YOU CRACK THAT SLEEVE NUT AND REMOVE THE FUEL RETURN LINE. THE FUEL PUMP IS LOCATED ON THE PASSENGER SIDE RIGHT NEXT TO THE BODY FRAME. PLACE THE DRAIN PAN DIRECTLY UNDER THE FUEL PUMP, LOSEN THE 5/8" SLEEVE NUT AND SLIGHTLY PULL THE MAIN FUEL LINE (METAL TUBE) AWAY FROM THE FUEL PUMP. NEXT TAKE THE SCREW DRIVER AND REMOVE THE CLAMP ON THE RUBBER HOSE, AND GENTLY PULL THIS HOSE AWAY FROM THE FUEL PUMP, NOTE: IF THE RUBBER HOSE IS DRY ROTTED OR SIGNS OF CRACKS THE YOU WILL NEED TO REPLACE IT. NEXT STEP TAKE YOUR 1/2" SOCKET AND REMOVE 2 1/2" BOLTS WHICH ARE INSTALLED ON THE RIGHT SIDE AND LEFT SIDE OF THE FUEL PUMP. REMOVE OLD GASKET AND DISGARD IT. BUT DONOT GET RID OF THE PLASTIC ADAPTER. ASSEMBLE: VIEWING THE ENGINE FROM THE FRONT TURN THE CRANK SHAFT CLOCKWISE. WHILE YOU TURN THE ENGINE CLOCK WISE HAVE A FRIEND USE HIS FINGER OR USE A BRASS DRIFT TO KEEP PRESSURE ON THE FUEL PUMP ROD BACK INSIDE THE BLOCK. WHEN THE FUEL PUMP ROD STARTS TO COME BACK OUT THIS MEANS THAT THE HIGH SIDE CAM LOBE IS IN THE BLOCK NOW YOU WOULD BE ABLE TO INSTALL THE NEW PUMP, AND NOW PULL OUT THE PUMP ROD AND PUT SOME GREASE ON IT AND PUT IT BACK INSIDE THIS GREASE WILL HOLD THE PUMP ROD INSIDE WHILE YOU MOUNT THE NEW PUMP ON. PUT A THIN LAYER OF RTV ON BOTH SIDE OF THE GASKET. PUT THE 1/2" BOLTS BACK ON AND DO NOT OVER TIGHTEN, THEN THE RUBBER HOSE WITH THE CLAMP, SNUG TIGHT ONLY. NOW PUT THE METAL TUBE ON AND HAND START THE THREADS MAKE SURE YOU DO NOT CROSS THREAD IT. START IT AND CHECK FOR LEAKS. JSOE N ENRIQUEZ
