Davco 233 water fuel separator filter compatibility

The Davco 233 water fuel separator filter is compatible with the following:

• FH230
• FH233
• Davco 382
• Cummins FS19729
• Fleetguard part #FS19727

The Davco 233 is recommended for use with EleMax filters, which have a three-layer filter technology.

Davco 233 water fuel separator filter removal

To remove the Davco 233 water fuel separator filter, you will need to follow these steps:

Firstly, locate the filter in your vehicle. The Davco 233 fuel filter is typically found in the engine bay, although the exact location may vary depending on the vehicle's year, make, and model. Once you have located the filter, you can begin the removal process.

Before starting, make sure you have the necessary tools and safety equipment, such as gloves and eye protection. It is also recommended to place a container or rag underneath the filter to catch any spilled fuel.

Next, you will need to relieve the fuel system pressure and disconnect the fuel lines from the filter. This can be done by closing the shut-off valves on the fuel lines and then loosening the fittings that connect the lines to the filter. Be careful when handling the fuel lines, as they may be under pressure.

After the fuel lines are disconnected, you can proceed to remove the filter. The Davco 233 filter is typically secured in place with a mounting bracket and bolts. Use the appropriate size socket or wrench to remove the bolts, and then carefully lift the filter out of the vehicle.

When removing the filter, be careful not to damage the O-rings or other sealing surfaces, as these are important for preventing fuel leaks. Once the filter is removed, inspect the O-rings and replace them if necessary.

Finally, you can install the new filter. Make sure that the new filter is the correct replacement for your vehicle and that all sealing surfaces are clean and free of debris. Secure the new filter in place with the mounting bracket and bolts, and then reconnect the fuel lines. Ensure that all connections are tight and secure before starting the engine.

It is important to note that working on fuel systems can be dangerous, and it is always recommended to refer to your vehicle's repair manual or seek the assistance of a qualified technician if you are unsure about any part of the process.
