Gasket Leakage On Aftermarket Fuel Filters{1261}
Usage:
3400 Series Engines
There have been reports that some aftermarket fuel filters do not seal correctly on the 3400 Series Engines. The gasket projection on these fuel filters is insufficient for correct sealing. Do not replace the filter base for this problem.
Use only a Caterpillar 4N5823 Fuel Filter on 3400 Series Engines to guarantee correct fuel filter performance.
