Sparta PN8011 Mechanical Fuel Pump

Mechanical Fuel Pump for Classic GM Applications

The Sparta PN8011 mechanical fuel pump is a standard replacement for older gasoline-powered Chevrolet and GMC trucks, vans, and passenger cars. Built with an aluminum housing and OE-focused fitment, it is designed for higher-mileage and earlier model vehicles that use a mechanical fuel delivery setup.

Sparta is distributed by Delphi, an OE full-line fuel supplier, and this pump reflects that background with a practical replacement design for service work on classic Chevrolet C10, C20, K10, K20, and GMC C1500 applications. The PN8011 is a direct mechanical fuel pump solution for gas engines that require consistent low-pressure fuel delivery.

Detailed Description

Sparta PN8011 is a mechanical fuel pump built for gasoline engines that rely on engine-driven fuel delivery rather than an electric pump. With two mounting holes, one hose-bead inlet, and two threaded outlets, it is configured for service on a range of classic GM platforms. The pump’s 6 to 8 psi pressure range and 30.0 average flow rating make it a practical replacement for maintaining steady fuel supply in older carbureted systems.

This part cross-references Airtex 40963 and Carter M6628 for the same application. It is a strong fitment match for vehicles such as Chevrolet C10, Chevrolet C20, Chevrolet K10, Chevrolet K20, GMC C1500, and GMC C2500 models that use a mechanical fuel pump setup. The PN8011 part number is also useful when searching for a replacement mechanical fuel pump for 1971-1986 Chevrolet and GMC applications.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal driving conditions
• Low fuel pressure in carbureted gasoline systems
• Replacement needs on worn mechanical pumps in classic trucks and cars
• Service issues on higher-mileage Chevrolet and GMC fuel systems

Installation Notes and Tips

Confirm the vehicle uses a mechanical fuel pump and verify inlet and outlet orientation before installation. Use the included gasket during mounting, and follow the instruction sheet for proper alignment and sealing. Check fuel line thread size and hose connection style against the existing setup before tightening the lines.
