Purolator Heavy Duty Fuel Filters

Today’s demanding engines need high performance and protection to keep vital engine components like fuel injectors clean and functioning well. Dirty fuel from water, bacteria, particulates and even wax are still a major concern when it comes to fuel systems. Purolator Heavy Duty Fuel Filters protect sensitive fuel systems' components, such as injection pumps and injectors, from damaging contaminants.

Purolator Heavy Duty Diesel Fuel Filters are more commonly fitted in primary and secondary configurations. Some systems operate with only a single filter, while other systems rely on a fuel filter and an optional fuel/water separator.

  • Primary Fuel Filters - usually mounted on the vacuum side and designed to capture larger particles and protect the transfer pump from abrasive contaminants

  • Secondary Fuel Filters – usually mounted on the pressure side of the transfer pump and designed to capture smaller contaminants and protect the sensitive injection equipment
