The Fleetguard FS1280 is a fuel/water separator filter used to help remove water and fuel-borne contamination before it reaches the engine's fuel injection system. It is used where the filter head or engine parts reference calls for FS1280 and is commonly cross-referenced with Donaldson, Baldwin, and WIX equivalents.
Key Features
- Fleetguard fuel/water separator filter
- Part number: FS1280
- Helps separate water from diesel fuel before it reaches injection components
- Supports routine fuel system maintenance
- Used for compatible diesel fuel filtration systems
- Cross references include Donaldson P551329, Baldwin BF1280, and WIX 33357
Engine Compatibility
Use where the existing filter, filter head, engine service record, or parts diagram calls for Fleetguard FS1280 or a verified equivalent. Fitment depends on the filter head, thread/seal configuration, fuel system layout, and engine application.
Fitment Notice
Confirm the existing filter number and filter head before ordering. Fuel/water separator filters can look similar but may differ in thread size, gasket diameter, overall height, drain configuration, or water-separation design.
When This Part Needs Replacement
Replace during scheduled fuel filter service, after contaminated fuel exposure, when water is found in the fuel system, or when symptoms such as hard starting, poor acceleration, rough running, fuel restriction, or loss of power appear.
Installation Notes
Pre-check the sealing surface and filter head before installation. Lubricate the gasket as recommended, tighten according to the filter manufacturer's instructions, and prime the fuel system after replacement. Inspect for leaks after startup and recheck once the engine has run.

Parts Desk Insight
Fuel/water separator cross references should always be matched against the filter currently installed, not just the engine model. The correct separator must match the filter head and sealing design so it can remove water properly without introducing air leaks or fuel restriction.
