Description

Keep clean fuel flowing to the engine with the Bosch Fuel Filter 77090WS. It installs as a direct-fit replacement across a broad Ford, Lincoln, Mazda, Mercury, and Merkur lineup — including the 1986-1997 Ford Aerostar, 1983-1997 Ford Mustang, 1992-1997 Ford Crown Victoria, 1983-1997 Lincoln Town Car, 2001-2006 Mazda Tribute, 1983-1997 Mercury Grand Marquis, and 1985-1989 Merkur XR4TI. With 57 total applications, see the Buyer's Guide tab for the full list.

Filters the fuel supply: traps rust, dirt, and debris carried in the fuel before they reach the injectors or carburetor.
Direct-fit replacement: designed to install on the listed applications.
Routine maintenance part: replace at the interval in your vehicle's service schedule to help maintain steady fuel delivery.

A restricting or clogging fuel filter can show up as hard starting, hesitation, stalling, or reduced power under load. If a dirty filter is the cause of those symptoms, replacing it with the 77090WS restores an unrestricted path for filtered fuel — diagnose the cause first, since these signs can also come from other fuel-system parts. Manufacturer part number 77090WS.

What are signs my fuel filter may need replacing?

Hard starting, hesitation, stalling, or reduced power under load can point to a restricted filter, though other fuel-system parts can cause the same symptoms — diagnose before replacing.

How often should I replace it?

Replace it at the interval listed in your vehicle's service schedule, or sooner if you notice restricted fuel-delivery symptoms.

Will this fix my rough running?

If a clogged fuel filter is the cause, replacing it restores an unrestricted filtered-fuel path; if symptoms remain, have the rest of the fuel system checked.
