FAQ:

Q: How does a diesel fuel water separator work?

A: A fuel water separator is a device that works to ensure clean fuel is delivered to the engine. Properly speaking, a fuel water separator is a small filtering device used to remove the water from the diesel fuel before it reaches to the sensitive parts of the engine.

Q: What does a diesel fuel filter do?

A: Diesel fuel filters usually are made in the shape of a basin or bowl. This means the filter curves down. Water collects in the bottom of the bowl, while an open/close valve at the bottom of the bowl allows the water to drain from the basin, leaving only water. It’s important to remember the chemistry of an engine.

Q: Where is the fuel filter on a diesel engine?

A: The air filter setup on most diesel engines is the same as on gasoline-powered vehicles, with the filter located inside the cold air collector box located under the hood.

Q: How does a marine fuel water separator work?

A: The fuel separator filters and removes water and solid contaminants from the fuel. It must remove the water before it reaches the fuel pump to work effectively. If the separator fails, any water in the fuel can wear away lubricants on the diesel fuel injectors.
