WATER IN FUEL FILTER: Draining off contaminants and water should get done on a regular basis. It is so simple that you don't need to be a mechanic to achieve this important task - which takes only a few minutes.
There is an important reason to drain water and dirt from a diesel engine water separator. It needs doing because diesel fuel becomes contaminated easier than gasoline.
Diesel fuel absorbs water more 'readily' than gasoline or petroleum does. That causes corrosion in the fuel delivery system.
You might have this simple gadget attached to your diesel engine. If so, it works by collecting water from the fuel system. It is 'conveniently' called a diesel fuel water separator. It is usually found on or near to the fuel filter in the engine bay.
If you cannot find your engine's fuel water separator you can have one installed. They are not expensive to fit. The benefits of installing a water trap could save you a huge bill on mechanical repairs.
As most diesel owners know already, a vehicle fuel system requires careful attention. Draining water from a diesel fuel filter separator should be part of scheduled regular service intervals.
That means before if the engine starts to misfire. That will help to prevent engine damage from the buildup of dirt and water in the fuel.
There are some 'self-cleaning' water separators in use nowadays. But, many older diesels will need to have water and contaminants drained away 'manually'.
Follow these simple steps if you want to remove excess water from the fuel supply line.
The big problem with water in diesel fuel is that internal corrosion blocks the diesel injectors. The result reduces the amount of fuel travelling into the engine combustion chambers. Diesel engine injector pumps and injectors have very small working clearances.

So, it is important to drain water in fuel filter of most diesel cars. You want to remove it before it reaches the diesel injection system. This simple task helps to move clean fuel through the supply line. In turn, that helps to keep your engine running smoothly.
