Replace the Element
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.

Stop the engine.
Turn the start switch to the "OFF" position.
Shut off the fuel tank supply valve to the engine.
If the primary fuel filter is equipped with a drain valve, open the drain valve in order to drain any fuel from the filter case. Close the drain valve.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Cat Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Cat Shop Supplies and Tools Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Remove the fuel filter bowl and wash the fuel filter bowl with clean diesel fuel.
Remove the fuel filter.
Clean the gasket sealing surface of the fuel filter base. Ensure that all of the old gasket is removed.
Apply clean diesel fuel to the new fuel filter gasket.
In order to maximize fuel system life and prevent premature wear out from abrasive particles in the fuel, use Cat fuel filters.Consult your Cat dealer for proper part numbers.
Install the new fuel filter. Spin the fuel filter onto the fuel filter base until the gasket contacts the base. Use the rotation index marks on the filters as a guide for proper tightening. Tighten the filter for an additional 3/4 turn by hand. Do not overtighten the filter.
Do not fill the fuel filters with fuel before installing them. The fuel would not be filtered and could be contaminated. Contaminated fuel will cause accelerated wear to fuel system parts.
Install the clean fuel filter bowl on the new fuel filter.
The water separator is under suction during normal engine operation. Ensure that the vent plug is tightened securely to help prevent air from entering the fuel system.
Open the fuel tank supply valve.
Start the engine and check for leaks. Run the engine for 1 minute. Stop the engine and check the engine for leaks again. Detection of leaks is very difficult especially if the engine is running. The primary filter/water separator is under suction. A leak will allow air to enter the fuel. The air in the fuel can cause low power due to aeration of the fuel. If air enters the fuel, check the components for overtightening or under tightening.
