Sparta PN8021 Mechanical Fuel Pump
Mechanical Fuel Pump for Corvette
The Sparta PN8021 mechanical fuel pump is a standard replacement for gasoline applications on 1970-1981 Chevrolet Corvette models. Built with an aluminum housing and hose-bead inlet, it is specified for older, higher-mileage vehicles that need consistent fuel delivery and OE-style fitment.

- Fits 1970-1981 Chevrolet Corvette
- Aluminum housing for standard replacement use
- Inlet outside diameter: 0.375 in.
- Threaded outlet design with 2 outlet ports
- Average flow rating: 35.0
- Operating pressure range: 7 to 9.0
- Mounting hardware and gasket included
OE-Style Fuel Delivery
Sparta PN8021 is a mechanical fuel pump built for vehicles that rely on engine-driven fuel delivery rather than an electric pump. It uses a hose-bead inlet, threaded outlet connection, and two mounting holes for a direct replacement layout on Chevrolet Corvette applications from 1970 through 1981. This part cross-references Airtex Fuel Pumps 41240 and Carter M6955 for the same application. The PN8021 is a practical choice when restoring fuel pressure and flow on a classic Corvette with a standard replacement pump.
Common Problems It Can Address
- Hard starting caused by weak fuel delivery
- Fuel starvation under normal driving conditions
- Low fuel pressure in a mechanical pump system
- Rough idle related to inconsistent gasoline supply
- Replacement needs on higher-mileage Chevrolet Corvette fuel systems
Installation Notes
Confirm inlet and outlet orientation before installation, and verify the 0.375-inch inlet size matches the fuel line connection. Use the included gasket during assembly and follow the instruction sheet for proper mounting on the engine. Because this is a mechanical fuel pump, installation should be matched to the vehicle’s original fuel system layout and pressure requirements.
Quality Assurance
Sparta is distributed by Delphi, an OE full-line fuel supplier with experience in fuel system fit and performance. PN8021 is positioned as a standard replacement part for earlier model vehicles, including Chevrolet Corvette applications, with OE-informed design and application coverage.
