How to Change a Fuel Water Separator Filter? A fuel water separator refers to a piece of equipment working to ascertain clean fuel is received by the engine. It is a tool filtering small particles and removes them before reaching the engine-sensitive parts.

Thus the performance and service life of diesel engines is not safe due to contaminants and water.

• The engine cylinder walls and components on contamination displace the lubricate coating of the injector high precision components. It causes surface pitting, tolerance erosion, fuel pressure loss, and result in poor performance.
• There is no way of preventing water from polluting fuel that condensation forms constantly within fuel tanks. It is a must to know How to Replace a Fuel Water Separator.
• A fuel water separator is a paper pleated element changing water particles into large droplets. Thereby, prevent small water particles and avoid from passing into the engine. Fuel water separator removes water from fuel and so it needs periodical checking.

Why Do You Need to Change Fuel Water Separator?

A fuel water separator benefits the engine as it removes particulates detrimental to the engine performance. There is a need to change the fuel water separator when you notice a clogged fuel filter.

The signs will be accelerating issues, trouble starting the car, engine misfires, frequent idling, strong odors, low performance, or engine misfires.

The need to change the fuel water separators implies you know How to Install a Fuel Water Separator. The fuel filter prevents remains and dirt from entering the fuel delivery system and its components.

It results in the engine’s high performance. Proper replacement and maintenance of fuel filters help boost the vehicle performance by 2% to 4%.

How to Change a Fuel Water Separator Filter?

Regular inspection and maintenance of the component minimize problems. In case a fuel water separator needs replacing, here are the steps.

Release Pressure

Disconnect the fuel pump that is in the relay box. Loosen the gas cap and take out the residual tank pressure. Allow the engine to run until it stalls.

Relieve all the pressure of the fuel from the tank; ensure to empty it by cranking it a few times. Reattach the fuel pump, but do not turn the key on. Re-pressurize the system.

Detach Hoses

Place under the fuel filter some rags. Exercise caution as you work around fuel. Stay away from flammable materials. Use under the filters a drip pan and a wrench to undo the fuel hose pipes.

Use a flat head screwdriver to pry the old fuel filter fuel lines. Detach the hoses and drain into the drainpipe any oil.

Take Out Fuel Water Filter and Separator

Get rid of the brackets from the filter and lift the filter from its holding position. Check for wear and tear in the fuel water separator.

If you find it is damaged, replace the fuel filter unit. Examine fuel hoses attached. If you find it is worn out, replace it with new.

Install Filter

Set up the filter such that its flat side is facing the engine. Connect the brackets to secure the filter and fasten the filters and the fuel hoses. Affix quality hoses, use clamps and tighten the fuel hoses, keep it torqued around 0.8 to 1.1-foot lbs.

Check and Start The Engine

Make sure there is no fuel residue or leaks. Check configuration and ascertain everything is fine. Start the engine.

Conclusion

Knowing change a fuel water separator filter is a must. These separators are installed in marine and automotive vehicles, besides industrial machines.

Water causes various problems to the engines of the vehicles such as grime, rust, fungus, bacteria, and hinders the engine functionality.

Thus, installing a filtration device, a fuel water separator, to remove water and other contaminants from the engine is essential.
