A fuel water separator is one of those vital components for any common rail diesel vehicle. It's an investment that rewards you handsomely -- preventing blockages or abrasions between the delivery pump and fuel injectors is critical to making your diesel vehicle run efficiently. The best maintenance is preventative maintenance -- it's cheaper and safer to prevent problems in the first place than it is to fix them when they occur.
