The fuel water separator filter is a key piece of equipment in the diesel engine. It removes tiny bits of water from the gas before it enters the engine.
This can help reduce wear on your engine by reducing corrosion, which can lead to leaks and other costly repairs.
In order to operate at peak performance, it’s important that this filter be changed regularly because old filters may not be able to do their job as well due to clogging or damage from contaminants in the fuel.
The frequency varies depending on location, driving conditions, and vehicle usage but typically ranges from every 60-120 days or 12-24 months for most drivers who don’t tow trailers or carry cargo in their trucks.
What is a Fuel Water Separator?
Fuel water separators are the processes that are used to remove the water from fuel oil. It is often considered an environmental hazard.
It is often used by trucks, ships, and trains for transportation of diesel fuel and home heating oil.
Reasons to change Fuel water separator filter
- The Fuel Water Separator filter can become clogged over time causing flow restrictions that raise the pressure of the filter.
- Over time, particles in the air can enter into the filter and accumulate to form a sludge-like mass that will cause serious flow restrictions on the Fuel Water Separator.
- The fuel inside of the tank can pass through to the waterside of the system due to this restriction caused by sludge buildup on the FWS Filter, which is not good for engine performance or Emission Control Devices (ECD).
Tools and Supplies to Install Fuel Water Separator Filter
If you have a fuel water separator filter or are looking to install one, you might be wondering what the tools and supplies are that are needed. The following information will help you determine what is needed for installation.
Shop towels – these should be soft enough so they don’t scratch the surfaces but absorbent enough to clean up excess water and not disintegrate as they go over rough surfaces like metal
Masking tape – this is used to hold things in place temporarily or may also be used as a sealant if it’s a thick adhesive tape
Knee pads – these make it easier on your legs and knees and prevent carpet and carpet padding from prematurely wearing out
Floor wraps – these protect your home from the studded legs that come from the bottom of your water separator
Screwdriver – a long shank flat head and Phillips is best since it makes it easier to get in tight spaces.
Socket set – a standard set with a few different sizes of sockets will make things easier when tightening or loosening nuts and bolts.
Pipe wrench – use this to hold the hoses in place while you tighten or loosen nuts and bolts
Hacksaw blade – if your water separator came with a plastic strap that holds the hoses in place, it’s very easy for it to break when you are trying to remove it. A hacksaw blade can easily cut through the plastic strap without damaging the water separator
Channel locks – these are pliers with serrated jaws that can provide a good grip on something and also prevent damage to the object being gripped
Now that you know what tools and supplies are needed, you can begin the installation process. Remember to always take your time and do things correctly, which can save you time and money in the long run.
How to Change a Fuel Water Separator
When it comes time to change your fuel water separator, it’s important to know how to do it properly.
Here, we’ll give you step-by-step instructions on how to do just that.
In order to change a fuel water separator, it is important to be aware of the make and model of your vehicle.
Once you have identified which make and model your car is, find out if the hose you want to replace is compatible with that type of car.
- A proper kit is needed to ensure that you have everything, including filters with clear plastic bowls or aluminum ones depending on what fuel source it will be used with (gas/diesel).
Disposable versions can also work but they won’t last as long before needing replacement.
- To prevent the risk of explosion, open hatches to ventilate your RV and close all fuel valves at both tank and supply line.
Drain or plug them with a bolt if necessary in order for you to safely dispose of its contents without any chance of fire.
- Mounting the head unit vertically will allow you to avoid having hoses that kink or make sharp turns.
Pilot holes should be drilled in order for sealant and screws are easily applied with self-tapping stainless steel fasteners when installing it onto a ship’s hull side as well.
- When installing the filter’s fuel fittings, use thread sealant to prevent leaks and smother some motor oil on gaskets or O-rings for element installation.
- Connect the two hoses together and make sure they are secure. Use a Coast Guard-approved A1 type of hose if needed, but only one single clamped at any time.
- Startup the engine and make sure there are no leaks at high rpm. Then take it for a quick sea trial around your house before going out on location to test-drive those new tires.
Fuel water separator filters are a must-have for any vehicle that runs on gasoline. They filter out contaminants from the fuel system, which leads to better performance and improved gas mileage.
This will save you money in both the short term with less maintenance required, as well as the long term because your engine is going to last longer without all of those nasty chemicals running.
