Baldwin BF46248 fuel filter for the Cummins X15 and other vehicles is a spin-on filter that removes contaminants from fuel before it reaches the engine. This Baldwin Filters fuel filter is replaced as a complete unit at service.
A clogged fuel filter can lead to hard starting, hesitation or a loss of power. Before you replace it, rule out an empty tank, a loose fuel line connection and a weak fuel pump, which can produce similar symptoms. One filter goes on each engine.
The vehicles it fits include the Cummins X15, the 2025-2026 Freightliner Cascadia L6-14.9L and the 2022-2026 International HX520 L6-14.9L.
