6.7 Powerstroke OE Cab & Chassis Sender and Pump Assembly | Motorcraft HC3Z-9H307-AS

Replace a weak rear-tank lift pump on a 6.7 Powerstroke cab-and-chassis truck with the genuine Ford / Motorcraft assembly. HC3Z-9H307-AS is the OE sender and pump unit for the aft-of-axle fuel tank. It sits in the tank, feeds the high-pressure pump, and includes the fuel-level sender. A failing module can cause hard start, no-start, low supply pressure, stalling, or a fuel gauge that reads wrong. This number supersedes HC3Z-9H307-D, HC3Z-9H307-AJ, HC3Z-9H307-S, PFS-1115, and PFS-1334.
