Bulletin Summary
THIS INFORMATION IS BEING ISSUED TO HELP DEALERS IDENTIFY APOTENETIAL SOURCE FOR FUEL CONTAMINATION. IF A CUSTOMER'S COMPLAINT LEADS TO THE DISCOVERY OF CONTAMINATED FUEL, THE SOURCE OF THE CONTAMINATION MUST BE FOUND AND REPAIRED. CONTAMINATED FUEL MAY RESULT IN MANY DIFFERENT FAILURES. SOME EXAMPLES OF THESE FAILURES ARE: PLUGGED FUEL FILTERS, POOR ENGINE PERFORMACE, CHECK ENGINE LIGHT ILLUMINATION, FUEL SYSTEM (LINES AND TANK) CORROSION (RUST), ETC... ISUZU'S FAILURE INVESTIGATIONS HAVE FOUND A COMMON OCCURANCE OF THE FUEL FILLER NECK BEING INSTALLED INCORRECTLY.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
