The modern Common Rail diesel engine has a complex fuel delivery system, which is sensitive to contamination from minute particles of dirt, air, water or wax. If these particles are not prevented from passing through the filter, they can quickly cause terminal damage to the injectors, pump or the entire system. By installing a filter that does not meet the vehicle manufacturer's specification, a workshop can invalidate the manufacturer's warranty and possibly be liable for any resulting damage.
The Delphi Diesel Common Rail filter meets OE specification and offers a Common Rail Filters brochure and poster that highlight the importance of using the correct filtration to assist fitters.
