Introduction To FL3Z-9H307-F Fuel Pump Module Assembly
The FL34-9H307-FK is an OE-standard complete in-tank electric fuel pump and fuel level sender module assembly engineered specifically for 13th-generation full-size pickup trucks. Stamped with engineering production code FL34-9H307-FK (and fully compatible with production revisions FL34-9H307-FF, FL34-9H307-FG, and FL34-9H307-DE), this module serves as a direct aftermarket replacement for catalog part numbers FL3Z-9H307-F, FL3Z-9H307-E, FL3Z-9H307-N.
Engineered as a drop-in in-tank fuel delivery unit, the FL34-9H307-FK integrates a high-efficiency electric turbine pumping unit, internal swirl pot reservoir, bottom intake filter strainer, precision ceramic card fuel level resistance sender with float arm, fuel pressure regulator / check valve, and an upper flange fitted with quick-connect fuel supply ports and a weatherproof multi-pin electrical connector. On twin-turbocharged 2.7L / 3.5L EcoBoost direct-injection engines and naturally aspirated 5.0L V8 powertrains, this low-pressure lift pump module continuously delivers a steady, pulsation-free volume of fuel from the main fuel tank to the engine-mounted camshaft-driven mechanical high-pressure fuel pump (HPFP) and fuel rail.

Step-by-Step Workshop Installation Guide
- Safety Preparation & Fuel Depressurization: Disconnect the negative battery terminal. Relieve fuel system residual pressure by removing the fuel pump fuse/relay and cranking the engine until it stalls.
- Fuel Tank Draining & Dropping: Siphon excess fuel from the tank into an approved container. Support the fuel tank with a transmission jack, disconnect the filler neck, vent lines, and wiring harness, unbolt the tank support straps, and gently lower the tank.
- Clean Module Flange Area: Thoroughly blow off and wipe away all dirt, mud, and road debris around the fuel pump locking ring to prevent contaminants from falling inside the tank.
- Remove Old Module: Using a specialized fuel tank lock ring tool, rotate the retaining lock ring counterclockwise. Carefully lift the module assembly upward, tilting it slightly to avoid bending the float arm.
- Inspect Tank & Install New Seal: Inspect the bottom of the fuel tank for dirt or water and clean if necessary. Place a new, clean sealing O-ring gasket onto the tank opening flange.
- Insert New Module Assembly: Lower the new FL34-9H307-FK module into the tank, guiding the float arm carefully. Align the top flange orientation notch with the tank slot, press down against the spring-loaded guides, reinstall the locking ring, and rotate clockwise until fully locked.
- Reinstall Tank & Pressure Test: Reconnect fuel supply lines until quick-connect tabs click audibly. Reconnect electrical harness, raise and secure fuel tank straps. Reconnect the battery, turn ignition to ON for 3 seconds (without starting) 3 to 4 times to prime the fuel system, check for leaks, and start the engine.

FAQ
Q1: What primary role does the FL3Z-9H307-F fuel pump module serve on for Ford F-150 EcoBoost engines?
For Ford F-150 EcoBoost engines, the FL3Z-9H307-F module acts as the low-pressure lift pump inside the gas tank. It delivers a constant 55-75 PSI fuel supply to the engine-mounted mechanical high-pressure fuel pump. This ensures steady fuel delivery under heavy boost and towing.
Q2: Why are part numbers FL34-9H307-FK and FL3Z-9H307-F completely interchangeable?
FL34-9H307-FK is the physical engineering casting code stamped onto the module top flange. Meanwhile, FL3Z-9H307-F is the primary catalog part number. Both represent the exact same complete drop-in fuel pump assembly, featuring identical fuel lines, connectors, and flow ratings.
Q3: What drivability symptoms and diagnostic fault codes occur when this fuel pump begins to fail?
A degraded sensor triggers diagnostic trouble code P0335 (Crankshaft Position Sensor A Circuit). Drivers encounter extended starter cranking, sudden engine stalling when warm, and hesitation during throttle tip-in. Additional symptoms include tachometer needle dropouts and illumination of the check engine light.
