FS20313 Fuel Water Separator — Volvo D11, D13 & Mack MP7, MP8

The FS20313 is a next-generation fuel/water separator cartridge featuring Fleetguard EleMax multi-layer water separation technology. Designed for Volvo D11 and D13 as well as Mack MP7 and MP8 engines, it provides three-stage water removal architecture for the most demanding diesel fuel environments.

Key Features

• EleMax three-stage water separation for superior moisture removal
• Cartridge-style element — 7.36" height × 4.50" outer diameter
• Rated flow of 2.91 GPM (11.00 L/min) for high-output diesel engines
• Engineered to meet or exceed Volvo and Mack OEM filtration requirements

Advanced Water Removal Technology

The EleMax system uses a coalescing pre-filter, a hydrophobic barrier, and a final polishing stage to remove both free and emulsified water from diesel fuel. This multi-layer approach delivers consistently low water levels downstream — critical for protecting modern common rail injection systems operating at extreme pressures.

Vehicle Compatibility

Direct OEM replacement for Volvo VNL, VNR, and VHD trucks (Volvo 24009059) and Mack Anthem and Pinnacle trucks (Mack 24009058).
