Baldwin Filters PF819 Fuel Filter Cartridge 27 micron

Baldwin PF819 27 Micron Fuel Filter

The Baldwin PF819 is a cartridge-style fuel filter designed for automotive and light-commercial fuel systems. Its 27 micron element traps fine contaminants before they reach injectors or carburettors. Mechanics and fleet operators use it to protect fuel pumps and maintain consistent flow. It installs in standard filter heads that accept this cartridge footprint.

27 Micron Rating and Element Capacity

The 27 micron media stops particles that cause injector wear while allowing adequate fuel volume for typical petrol and diesel engines. Service life depends on fuel cleanliness; heavily contaminated tanks will load the element faster and require shorter change intervals. The cartridge holds a practical amount of debris before restriction rises, giving a clear window for scheduled replacement. Flow drops noticeably once the media saturates, signalling the need for a fresh filter.

Cartridge Fitment and Included Seals

The unit measures 6 7/32 inches in height and length with a 3 15/16 inch outside diameter and a 7/8 inch inside diameter. Two attached gaskets and two furnished gaskets are supplied, covering the sealing surfaces needed for most common filter heads. No threads are present on the cartridge itself, so the mating head provides the clamping force. Verify the head dimensions and seal type before installation to ensure a leak-free fit.
