Baldwin Filters PF7761 Fuel Filter Cartridge 10 micron

Application fit

The Baldwin PF7761 is a cartridge-style fuel filter rated at 10 micron for fine particle capture. It suits diesel or petrol systems that call for a spin-on replacement with an 8-inch height and 3-23/32-inch diameter. Fleet operators and mechanics who need consistent filtration without oversized housings will find it matches the spec. It is not for buyers who require a different micron rating or a filter with integrated water-separator features.

Build integration

The element measures 8 inches long by 3-23/32 inches wide with a 1/2-inch and 1-25/32-inch inside diameter, so it fits standard cartridge bowls that accept those dimensions. An attached gasket, grommet and O-ring are included, removing the need to source separate seals during installation. Thread size is not applicable, meaning the filter seats by compression rather than screw threads. It does not suit housings that demand a threaded base or a larger outside diameter.

Capacity and headroom

At 10 micron the media stops fine contaminants that accelerate injector wear while maintaining flow for typical light- to medium-duty fuel systems. Service life depends on fuel cleanliness and volume; heavily contaminated supply will load the element faster and reduce change intervals. The filter offers no water-separation stage, so systems prone to free water need a separate separator upstream. It is not for high-flow applications that exceed the surface area of this cartridge size.
