Description
The Sierra 18-7844 is a marine aftermarket spin-on fuel filter/water separator element.
Why it matters
Diesel injection equipment is lubricated by the fuel that passes through it, so water and fine grit are what wear out injection pumps and injectors. The fuel filter is the cheapest insurance the fuel system has.
