If your truck is showing signs of weak fuel pressure, hard starts, or failed priming, this comprehensive kit gives you everything needed to rebuild your lift pump and Stage 1 fuel filter assembly in one shot — no hunting down individual components separately.

Key Features & Benefits

• Complete Rebuild Solution: Covers both the lift pump and Stage 1 fuel filter assembly simultaneously, so you restore the entire front end of your fuel system in a single service event rather than chasing failures one part at a time.
• New OE Replacement Fuel Pump Included: A brand-new fuel pump is part of the kit, directly addressing the root cause of weak fuel pressure and hard-start complaints common on aging Titan XD Cummins trucks.
• Fleetguard Filtration: The kit includes a new Fleetguard Stage 1 lower filter and a new Fleetguard under-hood filter — both industry-trusted filtration components designed to protect the high-pressure injection system from contaminants.
• All Necessary O-Rings Included: New O-rings for the fuel pump and Stage 1 filter assembly are provided, ensuring proper sealing and eliminating the risk of air intrusion or leaks that can compromise fuel system performance.
• Targets Known Failure Assemblies: Designed specifically to replace original fuel filter and fuel pump assemblies 16400-EZ40A and 16400-EZ40B, making identification straightforward for DIY installers and shop technicians alike.
• From Fleece Performance: Fleece Performance is a well-known specialist in diesel fuel system components, with an extensive catalog covering Cummins, Duramax, and Powerstroke platforms — giving Titan XD owners confidence they're using a purpose-built solution rather than a generic substitute.
