Detailed Description

Sparta PN4051 is a fuel pump hanger assembly engineered for specific GM full-size rear-wheel-drive vehicles, including the Buick Roadmaster and Chevrolet Caprice. It combines the pump, hanger, float arm, and sending unit into a single in-tank assembly, helping restore fuel delivery and fuel level signal performance in one service part. The unit uses a turbine-style electric pump, metal housing, and external strainer, with a nitrile rubber seal and included lock ring for service replacement.

Backed by Delphi distribution and OE-focused fuel system expertise, Sparta is positioned for higher-mileage and earlier model vehicles where correct fit and dependable fuel system operation matter. This part number, PN4051, also cross-references Airtex Fuel Pumps E3270 for the same application.

• Hard starting caused by weak or failing in-tank fuel pump output
• Fuel starvation under load from reduced pressure or flow
• Inaccurate fuel gauge readings from a worn sending unit
• Intermittent fuel delivery from aging hanger assembly components
• Fuel system service issues on Buick Roadmaster and Chevrolet Caprice models

Installation Notes and Tips
