The Fleece Performance FPE-SF-FMC-9907-SB SureFlo Performance Sending Unit is an engineered, drop-in replacement in-tank fuel canister assembly designed specifically for 1999–2007 Ford Super Duty F-250 and F-350 trucks (equipped with the 7.3L or 6.0L Powerstroke diesel) with short bed configurations. Built around an active reservoir canister bucket with dual one-way inlet check valves, a heavy-duty CNC-machined billet aluminum top plate, integrated -8 AN female O-ring ports, and updated electronic level-sensing rheostat, this unit completely eliminates the notorious "1/4-tank starvation" issue while accommodating stock or high-demand aftermarket lift pump fuel systems (such as FASS or AirDog) without cutting or drilling the factory poly fuel tank.

Problem Solved: Curing 1/4-Tank Fuel Starvation & Broken "Hutch/Harpoon" Pickups
The factory fuel pickup assembly inside 1999–2007 Ford fuel tanks relies on a fragile plastic pickup foot (the "duckbill" strainer). Over time, exposure to hot returned diesel causes this plastic to turn brittle and disintegrate, snapping off right around the 1/4-tank fuel level mark. Once fuel drops below this point, or when accelerating, braking, or driving on an incline, the exposed pickup tube draws air into the fuel system. On 7.3L and 6.0L HEUI engines, aerated fuel causes severe injector cavitation, loud cackle, loss of power, and injector failure. Additionally, factory fuel level sender cards corrode, causing erratic dashboard fuel gauge readouts. The Fleece SureFlo solves this by continually routing return fuel directly into an internal reservoir bucket equipped with one-way check valves, ensuring the pickup point remains submerged in fuel down to the absolute bottom of the tank.
Fitment
- 1999–2003 Ford F-250 Super Duty 7.3L Powerstroke Turbo Diesel (Short Bed / 6.75-ft Bed)
- 1999–2003 Ford F-350 Super Duty 7.3L Powerstroke Turbo Diesel (Short Bed / 6.75-ft Bed)
- 2003–2007 Ford F-250 Super Duty 6.0L Powerstroke Turbo Diesel (Short Bed / 6.75-ft Bed)
- 2003–2007 Ford F-350 Super Duty 6.0L Powerstroke Turbo Diesel (Short Bed / 6.75-ft Bed)
- Fitment Note: Specifically engineered for pickup trucks equipped with short beds (6.75-ft). Does not fit 8-ft long beds (use part # FPE-SF-FMC-9907-LB), Excursion rear tanks, or Cab & Chassis aft-axle tanks.
Safety & Tank Access: Run fuel down as low as possible before starting. Either drop the fuel tank using a transmission jack or unbolt the truck bed (six or eight T50/T55 bed bolts) and slide/tilt it back to access the tank top module without dropping the tank. Factory Unit Removal: Disconnect the electrical wiring harness connector. Use a 5/16" and 3/8" fuel line disconnect tool to release the factory supply and return lines. Thoroughly blow away dirt and road grime from the tank locking ring flange using compressed air. Using a brass drift punch and mallet or a dedicated fuel tank lock ring tool, rotate the lock ring counter-clockwise to unlock. Carefully withdraw the factory sending unit and discard the old tank seal. Tank Sump Cleaning: Inspect the inside floor of the fuel tank with a flashlight. Siphon out any settled sediment, slime, or broken factory plastic foot debris from the tank floor before proceeding. Float Arm Assembly: Snap the included fuel float arm securely into the side pivot bracket on the Fleece SureFlo assembly, verifying the wiper arm sweeps smoothly across the rheostat board without binding. Canister Insertion & Sealing: Seat the supplied new O-ring squarely into the fuel tank flange sealing groove. Carefully insert the SureFlo bucket assembly at an angle into the tank opening so the float arm clears the baffle. Press the billet aluminum top plate down flat against the tank flange, clocking the ports toward the factory fuel line routing direction. Lock Ring Installation: Reinstall the factory retaining lock ring over the billet cap. Rotate the lock ring clockwise with your tool until it reaches the positive factory stops. Plumbing Connections: Factory Fuel Lines / Stock Lift Pump: Thread the included factory quick-connect adapter fittings into the -8 AN ORB ports on the billet cap. Snap the factory push-lock supply and return lines firmly onto the adapters until locked. Aftermarket Lift Pump (FASS / AirDog): Thread standard -8 AN male to -8 AN ORB fittings (sold separately) directly into the cap ports to plumb custom 1/2" supply and return lines, bypassing factory quick-connects entirely. Final Wiring & Verification: Plug in the factory electrical connector. Add at least 5 gallons of fresh diesel fuel. Turn the ignition key to "RUN" (KOEO) for 30 seconds to prime the system and observe the dashboard fuel gauge to verify accurate level calibration. Start the truck and inspect all top fittings for complete, leak-free operation.
