Baldwin Fuel Water Separator Filter P/N:BF1391-O
Baldwin Filters
Baldwin BF46182-O fuel water separator filter for the 2018-2020 Mack Granite 6-cylinder 10.8L, the 2019-2021 Granite 6-cylinder 12.8L and other vehicles separates water from the fuel before it reaches the engine.
Hard starting, power loss or hesitation under load can mean a clogged separator, though a weak fuel pump or a leaking fuel line can produce the same signs, so look at those two before replacing the filter.
It is listed for a wide range of Mack and Volvo models, including the 2020-2021 Mack Pinnacle 6-cylinder 12.8L and the 2018 Mack Anthem 6-cylinder 12.8L, the 2018-2020 Anthem 6-cylinder 10.8L and the 2020 Anthem 6-cylinder 12.8L.
