Detailed Description

Sparta PN4058 is a fuel pump hanger assembly engineered as a standard replacement for higher-mileage and earlier-model vehicles. Distributed by Delphi, an OE fuel supplier, this assembly is built for fit and performance on 1987-1990 Jeep Cherokee and 1987-1990 Jeep Wagoneer models. The package includes the hanger assembly with float arm, seal, lock ring, and instruction sheet, along with the fuel pump and sending unit already integrated.

This assembly uses a turbine pump design, a nitrile rubber gasket or seal material, and an external strainer for in-tank fuel pickup. It features one inlet, two outlets, a 0.375-inch outlet outside diameter, and a pin-style terminal layout with a female rectangle connector. This part cross-references Airtex Fuel Pumps (e.g., E7006, E7091S) for the same application.

Common Replacement Reasons

• Fuel pump failure causing hard starting or no-start conditions
• Inaccurate fuel level readings from a worn sending unit
• Low fuel pressure or inconsistent fuel delivery
• Fuel starvation under load from a failing in-tank assembly
• Noise or intermittent operation from an aging electric pump

Installation Notes

Verify tank access, connector style, outlet routing, and pressure requirements before installation. Replace the seal and lock ring during service, and confirm the float arm moves freely after the assembly is positioned in the tank. Use the included instruction sheet for assembly orientation and electrical connection details.

Quality Assurance

Sparta is distributed by Delphi, an OE full-line fuel supplier with application knowledge focused on fit and performance for earlier-model and higher-mileage vehicles. PN4058 is built as a standard replacement fuel pump hanger assembly for direct service use on the listed Jeep applications.
