Sierra 18-7714 Inline Fuel Filter, White, Replaces Mercury Marine 35-877565T1

The Sierra 18-7714 is an inline fuel filter designed to trap contaminants and debris in the fuel line before they reach the carburetor or fuel injection system, helping protect the engine from dirt, rust particles, and other fuel-borne debris. Finished in white with a metal outer housing, this filter is built as a direct equivalent to the Mercury Marine 35-877565T1 fuel filter, making it a straightforward replacement for boat owners maintaining Mercury Marine fuel systems. Installed inline within the fuel delivery system, it is a simple, low-cost maintenance item that supports consistent fuel flow and helps prevent clogging or damage to downstream fuel system components. Sierra manufactures this filter under a limited warranty and packages it as a single-unit replacement part, making it easy to keep spares on hand for routine service intervals. Boat owners performing scheduled fuel system maintenance or replacing a worn or clogged filter can use the Sierra 18-7714 as a like-for-like swap without modifying existing fuel lines.
