The Fleece Performance SureFlo performance sending unit is a direct replacement designed for 1999-2007 Ford F-250 and F-350 Powerstroke trucks with long beds. It is engineered to repair malfunctioning fuel level sensors or enable custom fuel line routing directly to the tank. Constructed with durable materials, this unit features factory-style quick connect fittings for a clean, no-cut installation compatible with aftermarket lift pumps. Unlike OE units that only draw fuel through a pickup tube, the SureFlo draws from and returns fuel to the bucket assembly, ensuring consistent fuel delivery and eliminating common quarter-tank issues. The inclusion of one-way check valves allows fuel flow at low levels, and the heavy-duty billet aluminum cap enhances durability. It also incorporates new fuel level electronics and a float, with universal -8 AN ports for professional plumbing of custom fuel setups. This unit replaces multiple Ford part numbers and is protected under US Trademark Reg. No. 6,878,858, with patents pending.
Designed for 1999-2007 Ford F-250 and F-350 Super Duty trucks with 7.3L or 6.0L Powerstroke engines and long beds, this drop-in replacement fits seamlessly without tank modifications.

Suitable for street, towing, and off-road use, this performance sending unit ensures accurate fuel level readings and consistent fuel flow, supporting enhanced vehicle performance and reliability.
