Newer Caterpillar engines equipped with electronic fuel injection systems previously using the FF1011 now use the Hastings FF1079, while the older Caterpillar engines with mechanical fuel injection systems still use the FF984 (Caterpillar 1P2299).
The FF1011 provided a direct replacement for the Caterpillar 1R0740 fuel filter. The 1R0740 was considered an upgrade to the Caterpillar 1P2299 fuel filter because it provided longer service life. Hastings Filters met the performance of the 1R0740 by designing the FF1011 with the capacity to provide 20% longer service life than the FF984. However, the design of the FF984 fuel filter eventually evolved to match the service life of the FF1011. The current FF984 and FF1011 utilize the same filtering element, providing equal filtration efficiency and filter service life. With the performance of these two filters being equal, the logical choice is to obsolete one of the part numbers to save on inventory and manufacturing costs. Caterpillar's introduction of the 1R0750 provided a high efficiency fuel filter that is now used in place of the 1R0740 on Caterpillar engines equipped with electronic fuel injection systems. |
Please refer to Engineering Bulletin 98-2 for more information regarding the high efficiency fuel filters. Since the 1P2299 is still used on Caterpillar engines with mechanical fuel injection systems, there was no need to continue the 1R0740 fuel filter. Therefore, Caterpillar discontinued the 1R0740. In response to Caterpillar's action, Hastings Filters chose to obsolete the FF1011 and continue the FF984. This also allows us to consolidate two identical part numbers into one and remain consistent with Caterpillar's recommendations.
Please make note of this change in your current Hastings Filters Application Guide and look for these changes in your future orders of Hastings filters. Performance Testing: Fuel
