Beck/Arnley Fuel Filter P/N:043-0963
Beck/Arnley 043-0439 fuel filter for the 1977-1978 BMW 320i and other vehicles strains particles out of the fuel on its way to the engine.
Hard starting, hesitation or weak power under load can mean the filter is restricted, but a tired fuel pump or another fuel-system fault can show up the same way. Find the cause first. With the engine off and cool, look over the filter and its connections for wetness, dents or damage, and leave any test that opens the fuel line to a shop. A car takes one filter.
It fits the 1977-1978 BMW 320i and the 1975-1977 Audi Fox, and it is a fuel filter for the 1974-1977 Porsche 911 H6 2.7L. It matches OE form, fit and function. If your car is not one of these, find it in the "Vehicles it fits" section to see whether this filter is matched to it.
