BDFHYK Fuel Pump Assembly E3559M replaces OE units to restore reliable fuel delivery for 2002–2004 Chevrolet Tahoe and GMC Yukon V8 5.3L vehicles.

When an aging fuel pump starts to cause hard starts, engine sputter, or loss of power, swapping in a direct-fit replacement can return drivability without extensive troubleshooting. This BDFHYK assembly is built to match original equipment fit and function for select 2002–2004 GM full-size SUVs with the 5.3L V8. It combines a corrosion-resistant housing, an integrated filter, and OE interchange numbers so you can confirm compatibility with your vehicle.

How does this pump restore proper fuel delivery?

The assembly draws fuel from the tank, pressurizes it, and sends it through the fuel lines to the engine while working with the vehicle’s pressure regulator. Replacing a failing unit removes flow restrictions and inconsistent pressure that cause rough idle or stalling.

• Direct-fit design intended for factory mounting points and electrical connector types.
• Integrated filter element captures debris and helps protect the injectors and regulator.
• Precision internal components help maintain steady fuel pressure under load.
