LEVER 7P3414 - Caterpillar

pressure gauges that measure fuel pressure pre-filter and post-filter are provided on the factory offered fuel train.The difference between the pre-filter and post-filter gauge readings indicate the difference in fuel pressure across the filter. The differential pressure increases as the fuel filter becomes plugged.Operate the engine at the rated rpm and at the rated load. Check the fuel filter differential pressure. Service the fuel filter and o-rings when the fuel filter differential pressure reaches 10 kPa (1.5 psi).For instructions, refer to Special Instruction, REHS8184, "Installation and Maintenance of the Fuel System for Certain Gas Engines".
