Sierra 18-7951 Fuel Water Separator Filter Kit, 1/4 Inch Aluminum with Metal Drain Bowl, 10 Micron
Sierra 18-7951 Fuel Water Separator Filter Kit, 1/4 Inch Aluminum with Metal Drain Bowl, 10 Micron
The Sierra 18-7951 is a 1/4 inch fuel water separator filter kit built with an aluminum filter head and a metal drain bowl, rated at 10 microns for filtering water and contaminants out of gasoline fuel before it reaches the engine. The metal drain bowl allows accumulated water to be drained off periodically, which extends the service life of the filter element between changes. Because the bowl is metal rather than clear plastic, this kit is suited to above-deck outboard installations; USCG regulations require the flame-resistant metal bowl design specifically for any fuel filter mounted below deck.
Each kit is a complete install-ready package rather than just a replacement cartridge: it includes the 18-7919 filter element, an 18-7853-1 mounting bracket, the 18-7924 metal drain bowl, and two 18-4256 1/4 inch pipe plugs for capping unused ports on the filter head. This makes the 18-7951 suitable for a first-time fuel filter/water separator installation as well as a full assembly replacement, not just a filter swap.

Frequently Asked Questions
What does the Sierra 18-7951 kit include? The kit includes the 18-7919 filter element, an 18-7853-1 mounting bracket, the 18-7924 metal drain bowl, and two 18-4256 1/4 inch pipe plugs, so it is a complete filter head and bowl assembly rather than just a cartridge.
Is the drain bowl on the 18-7951 plastic or metal? It is metal, not clear plastic. The 18-7951 kit uses the 18-7924 metal drain bowl, which USCG regulations require for any fuel water separator mounted below deck.
Can this filter be installed below deck? Yes, the Sierra 18-7951 uses a flame-resistant metal drain bowl, which is the design USCG regulations require for below-deck installations; above-deck outboard installations are also suitable.
What micron rating is the 18-7951 filter? The 18-7951 kit carries a 10 micron rating, filtering water and particulate down to that size before fuel reaches the engine.
What fuel line size does the 18-7951 fit? This kit is built for a 1/4 inch fuel line and includes 1/4 inch pipe plugs (18-4256) for capping unused ports on the filter head.
How much does the Sierra 18-7951 weigh? The complete kit weighs 3.04 pounds.
What is the replacement filter element for the 18-7951 kit? The filter element used in the 18-7951 kit is the Sierra 18-7919, which can be ordered separately for future filter changes once the bracket and bowl are already installed.
Is the 18-7951 the same as the stainless steel version? No. The stainless steel equivalent with a metal drain bowl is a separate kit, part number 18-7938; the 18-7951 uses an aluminum filter head instead of stainless steel.
Why does the bowl need to be drained periodically? Water that collects in the metal bowl of the 18-7951 needs to be drained off to keep the filter working effectively and to extend the service life of the 18-7919 filter element.
Does the 18-7951 kit come with mounting hardware? Yes, it includes the 18-7853-1 bracket for mounting the filter head, along with the pipe plugs needed to seal unused ports.
Is this a genuine Sierra part? Yes, the 18-7951 fuel water separator kit is a genuine Sierra part, identified by UPC 808282226435 and covered by Sierra's limited warranty.
