Description
When your commercial truck or bus starts losing power or the engine isn’t running as smooth as it used to, there’s a good chance your fuel filter is loaded up with dirt, water, or debris. Clean fuel is what keeps these hardworking engines running right and protects those expensive injection components from damage. This Baldwin PF9803 replacement gets your fuel system back to filtering like it should, keeping you rolling when deadlines matter.
What You’re Getting
- Compact 3 11/16 inch length fits tight engine compartments without clearance issues

- Baldwin quality construction designed to handle commercial duty cycles and temperature swings
- Direct replacement filter that installs quickly with basic tools

Built for Commercial Duty
This filter is specifically designed for the Mitsubishi 4M50 engine found in medium-duty trucks, delivery vehicles, and transit buses. These engines work hard every day in stop-and-go traffic, highway hauling, and urban delivery routes where reliable fuel delivery is critical for keeping schedules and making money.
Made to Last
Baldwin has been making filters for decades, and they understand what it takes to handle commercial conditions. The housing stands up to engine vibration and temperature swings without failing, while the filter media does its job of keeping contaminants out of your fuel system season after season.
Installation Notes
This is a direct spin-on replacement that installs in minutes. Apply a thin coat of clean diesel fuel to the gasket before installation, then hand-tighten only until the gasket contacts the mounting surface. Over-tightening can damage the seal and cause leaks. Always drain the old filter properly to avoid spills in your shop.
