Detailed Product Overview

Sparta PN8040 is distributed by Delphi, the OE full-line fuel supplier, and is aimed at higher-mileage and earlier model vehicles where dependable mechanical fuel delivery matters. This pump uses a mechanical design with threaded connections for one inlet and one outlet, making it a direct-style service part for carbureted gasoline systems. It is a practical choice for restoring fuel pressure and flow on vehicles such as the Chevrolet Bel Air, Chevrolet Impala, Chevrolet El Camino, GMC G1000 Series, Pontiac LeMans, Pontiac Tempest, and Chevrolet Malibu. This part cross-references Airtex Fuel Pumps (e.g., 6790, 40253) for the same application.

What This Fuel Pump Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal driving conditions
• Low fuel pressure in a mechanical pump system
• Inconsistent fuel flow to the carburetor
• Replacement needs on worn original equipment pumps

Installation Notes and Tips

Confirm the vehicle uses a mechanical, gasoline fuel pump with threaded inlet and outlet ports before installation. Verify mounting hole count, pressure range, and line routing against the original unit. A new gasket or seal is not included, so plan to reuse only serviceable sealing components or source the correct seal separately. Use the included instruction sheet and follow factory service procedures for proper alignment and torque.
