Description

The Sierra 18-7718 is an in-line fuel filter designed for under-cowl installation. It features sonically sealed end caps and OEM-matched filter media for reliable performance. This filter is approved for use with ethanol-based fuels and is rated at 30 microns.

It is recommended that filters be inspected regularly and replaced every 50 hours of operation or at least once per year, ideally during winterization. The Sierra 18-7718 is interchangeable with several Mercury Marine part numbers, including 35-879885T and 35-879885Q.
