Cummins Inc is conducting a campaign of ISB engines Model year '98-'02 installed in school buses, transit buses and emergency vehicles in the United States and Canada due to a possible problem with the fuel lift pump. Cummins Inc has determined that a small percentage of these engines may experience a stall condition. Approximately 43,000 engines are involved, the vast majority of which are school bus engines.

Within the campaign population, Cummins Inc will replace the fuel lift pump with an improved design at no cost to the customer. Cummins Inc will also at no cost to the customer, install a fuel pressure switch coupled with the existing check engine light to warn drivers of low fuel pressure conditions. In addition to replacing the fuel lift pump and installing the fuel pressure switch, under a new Customer Asurance Plan Cummins Inc will replace all fuel injection pumps manufactured between Jan. 2001 and Dec. 2003 due to fuel pump timing bushing failures which result in Fault Code 368. All fuel injection pumps that do not qualify for replacement will be covered by a 10-year (from engine date-in-service) extended coverage for parts only.

I did NOT need an engine number but I did some digging around and found a valid BlueBird Bus engine number that you can use if you get a distributor that requires it. Engine # 56561524 This is a 1999 manufacture date 250 Encore ISB 5.9 Cummins engine.
