VSE Fuel System Saver 2020-2026 GM 6.6L L5P Duramax DRW Crew Cab Long Bed

The VSE Fuel System Saver replaces the single factory fuel/water filter on the 2020-2026 6.6L L5P Duramax with a two-stage filtration block that runs off the factory in-tank lift pump. This listing is the dual rear wheel crew cab long bed pickup configuration.

Key Features

• Two-stage filtration: a Baldwin BF1280 water separator pre-filter followed by a Baldwin BF7633 post filter
• Pre-filter provides 18% more surface area than the stock filter and 95% efficiency at 20 micron
• Post filter catches fine debris down to 4 micron at 99% efficiency
• Service interval of 15,000+ miles on both filters
• Port-matched machined aluminum filter block with lower differential pressure than the factory filter, rated by VSE for up to 1000 RWHP
• Retains the factory lift pump, fuel heater and water-in-fuel sensor, so no calibration changes or blocked P-codes are required
• Donaldson cross reference: P551313 (fuel) and P551329 (water separator)
• Lifetime warranty against fit and finish
