Fleece Performance SureFlo Performance Fuel Tank Sending Unit – 1998-2002 5.9L Cummins (FPE-SF-CUMM-9802)

Eliminate ¼-tank fuel starvation and cavitation issues when running an aftermarket lift pump. The Fleece SureFlo Performance Sending Unit is a direct-fit upgrade designed specifically for 1998-2002 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins (both 12-valve and 24-valve).

Unlike traditional draw straws or tank sumps that require cutting or drilling, the SureFlo drops straight into the factory sending unit location. It uses OEM-style quick-connect fittings so you can retain your stock fuel lines or easily convert to custom plumbing with the included -8 AN ports. Fuel is drawn from — and returned to — a sump-style bucket at the base of the unit. Integrated one-way check valves keep the bucket primed even at very low fuel levels, ensuring your external pump (FASS, AirDog, etc.) always receives a solid column of fuel instead of air.

Key Features

• Direct bolt-in replacement — no tank modification required
• Heavy-duty billet aluminum top plate
• New fuel level sender and float assembly (20-220 ohm range)
• Factory-style quick disconnects + universal -8 AN ports for custom fuel systems
• Sump-style bucket with one-way check valves eliminates ¼-tank problems
• New seal/gasket included
• Compatible with popular external lift pumps up to approximately 200 GPH

Fitment

• 1998–2002 Dodge Ram 2500 / 3500
• 5.9L Cummins (12-valve and 24-valve)

Ideal for trucks running an aftermarket lift pump, or as a high-quality replacement when the original sender has failed. The SureFlo delivers a clean, professional installation while solving one of the most common fuel system headaches on modified 2nd-gen Cummins trucks.
