Mercury – Fuel Filter | Fuel System Component | Filter Assembly with Gaskets | 49088T2

Overview

Fuel that’s even slightly dirty can cause all kinds of trouble — from hard starts to power loss. The Mercury Marine 49088T2 Fuel Filter helps keep your fuel clean so your MerCruiser 4- or 6-cylinder engine runs the way it should. Designed for models with a Rochester 2-barrel carburetor and Carter fuel pump, this filter traps water and fine debris before they can reach the carb or pump. It’s an easy swap using basic tools and comes with new gaskets for a clean, tight seal. Reliable, simple, and made for the long haul — this is the kind of small maintenance that makes a big difference on the water.

Performance & Real-World Benefits

This 49088T2 filter does more than just keep fuel clean — it keeps your boat dependable. By filtering out moisture and dirt, it protects the carburetor jets and pump from clogs, rust, and corrosion. You’ll notice smoother starts, steadier throttle response, and consistent power, even on long runs.

Swapping this filter once a season is quick and inexpensive but pays off in fewer problems and more time on the water. It’s one of those simple maintenance steps that helps your engine perform like new.

Why Choose Mercury OEM

The Mercury 49088T2 is a genuine factory filter, not an aftermarket substitute. It’s engineered for the right balance of fuel flow and filtration — something generic filters often get wrong. Mercury tests every filter to handle marine pressure, vibration, and ethanol-blended fuels, ensuring long-term reliability.

With Mercury OEM, you’re using the same filter your engine was built with — one that fits perfectly and protects better in real boating conditions.
