Fuel Water Separators

When it comes to the safety and performance of your engine, fuel water separators are an important consideration. As these are simple and economical installations for a host of trucks and heavy vehicles with diesel engines, they can provide an additional layer of protection to the constituent parts and ensure both maximum and continued functionality.

A fuel water separator is a type of fuel filter that removes any water or moisture build-up in diesel, to minimise issues that may otherwise occur in the fuel injection nozzle and other parts of the engine and extend service life. This is typically performed by detecting the difference in densities between water and fuel. The right device can also help to preheat fuel, which can increase the filtering process and minimise wax formation.

Why is water in fuel a bad thing?

The main issue that can arise when water is in your fuel is that it will affect the performance of diesel in terms of lubrication. When fuel isn’t providing the right level of greasiness to the internal components of the engine, wear will occur faster and performance will decrease. The presence of water can also cause rusting throughout the engine, unwanted microbial growth that could lead to sludge, and has the potential to freeze diesel if your truck or heavy vehicle is left in cold weather.

All of these instances can be costly if damage occurs and at the very minimum, you could see lesser fuel consumption and minimised performance. The good news is that the right fuel water separator installed in your fuel line can all but negate these issues.

As fuel water separators can perform important functions that can prolong the lifespan of truck engines and ensure continued functionality, it can be important to get the right model for your vehicle. Right here at Big Rig World, we not only have a wide range of fuel water separators for you to peruse below, but we also have expert technicians on hand to provide support and assistance when purchasing, during installation, or when inquiring about a host of issues.
