INOPERATIVE FUEL INJ. CLEANER ESSENTIAL TOOL J-35800

A POSSIBILITY EXISTS THAT SOME OF THE SUBJECT TOOLS MAY HAVE BEEN ASSEMBLED AND SHIPPED TO DEALERS WITH THE FUEL PICK UP TUBE RETAINING SCREW NOT FULLY TIGHTENED. THIS COULD CAUSE AN INTERNAL LEAK AND NOT ALLOW THE GASOLINE/CLEANER MIXTURE TO ENTER THE ENGINE FUEL SYSTEM. THIS POSES NO DANGER OR FIRE HAZARD.

SINCE THE TOOL IS SHIPPED WITH THE FUEL HOSE, GAGE, CHECK VALVE AND BRASS TEE FITTING UNASSEMBLED AND NOT INSTALLED ON THE TANK, THE RETAINING SCREW SHOULD BE CHECKED PRIOR TO ASSEMBLY. SEE FIGURE 1.

IF THESE PARTS HAVE ALREADY BEEN ASSEMBLED REMOVE AS SHOWN IN FIGURE 1.

NOTE: USE BACK UP WRENCHES ON ALL FITTINGS WHEN REMOVING AND INSTALLING.

1. TIGHTEN RETAINING SCREW AS SHOWN IN FIGURE 1.

2. REINSTALL PARTS USING A GOOD QUALITY THREAD COMPOUND ON ALL THREADS PIROR TO ASSEMBLY.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
