Detailed Description

Sparta PN4018 is a fuel pump hanger assembly engineered for direct replacement in select Chevrolet S10 Blazer, GMC Jimmy, and Oldsmobile Bravada models. It combines the in-tank pump, hanger, float arm, and sending unit into one assembly, helping restore fuel delivery and fuel level signal performance in vehicles that need a complete replacement unit. This part cross-references Airtex Fuel Pumps E3625S for the same application.

As a standard replacement part distributed by Delphi, Sparta focuses on fit and performance for earlier model, higher-mileage vehicles. The assembly uses a turbine-style electric pump, a rectangle connector with male connector gender and female terminal gender, and a 2-terminal layout. The package also includes the seal, lock ring, external strainer, and two O-rings for service work on the fuel tank opening.

What It Helps Address

• Hard starting caused by weak or failing fuel delivery
• Low fuel pressure from a worn in-tank pump
• Inaccurate fuel gauge readings from a faulty sending unit
• Fuel starvation under load or during acceleration
• Noise or inconsistent operation from an aging pump assembly

Installation Notes

Fits 1992-1994 Chevrolet S10 Blazer, 1992-1994 GMC Jimmy, and 1992-1994 Oldsmobile Bravada. Verify tank configuration, connector style, outlet size, and electrical connection before installation. Replace the tank seal and lock ring during service, and follow the included instruction sheet for proper hanger positioning and float arm alignment. Because this is an in-tank assembly, clean the tank and inspect the fuel lines before reassembly.

Quality Assurance

Sparta is distributed by Delphi, an OE full-line fuel supplier, and is positioned for fitment and performance on earlier model vehicles. PN4018 is built as a specific-fit, standard replacement fuel pump hanger assembly for direct service use.
