Chevy Small Block 6-Valve 9 PSI 110 GPH Mechanical Fuel Pump - Chrome

• Six-valve mechanical pump design improves flow and check-valve performance

• 110 GPH flow at 9 PSI for higher-demand carbureted setups

• Requires a 5.75" fuel pump pushrod for proper SBC operation

• 0.500 in. NPT ports, larger than TSP's standard 80 GPH/6 PSI SBC pump

Built for carbureted Chevy Small Block V8 (Gen. I) applications demanding higher fuel flow, this mechanical fuel pump uses a six-valve internal design to improve flow consistency and check-valve performance over a standard mechanical pump. It delivers 110 GPH at 9 PSI — a step up from TSP's standard 80 GPH/6 PSI SBC mechanical pump, suited to carbureted setups needing more fuel volume without the higher pressure of TSP's 130 GPH/12–16 PSI six-valve pump.

As a mechanical pump, it draws its pumping action directly from the engine's camshaft via a pushrod — no electric pump, wiring, or power source is needed. This unit requires a 5.75" fuel pump pushrod for proper operation on Small Block Chevy engines, and uses larger 0.500 in. NPT inlet/outlet ports to support the higher flow rate.

This pump is designed for carbureted fuel systems and is not intended for EFI applications unless used with a properly designed and regulated fuel system conversion.

Applications
Fits Chevrolet Small Block V8 Gen. I engines (262–400 CID), commonly found in Camaro, Corvette, Chevelle, Nova, C/K trucks, and full-size Chevrolet applications — a middle-tier option between TSP's standard-flow and highest-flow SBC mechanical pumps.

Installation
Requires a 5.75" fuel pump pushrod for correct operation on Small Block Chevy engines. Confirm 0.500 in. NPT port sizing matches your fuel line setup, and verify mounting pattern, pump arm style, and line clearance before installation. Mounting hardware is not included.

Is this an electric or mechanical fuel pump?
This is a mechanical fuel pump that is driven directly by the engine's camshaft through a fuel pump pushrod. It requires no electrical wiring or external power source.

What does "six-valve" mean for this pump?
The six-valve design refers to the pump's internal check valve arrangement, which helps improve fuel flow consistency and pumping efficiency compared to a conventional mechanical fuel pump.

How does this compare to TSP's other SBC mechanical pumps?
This pump delivers 110 GPH at 9 PSI, providing greater fuel flow than TSP's standard 80 GPH/6 PSI mechanical fuel pump while operating at a lower pressure than TSP's high-performance 130 GPH/12–16 PSI six-valve model.

What pushrod does this pump require?
This pump requires a 5.75-inch fuel pump pushrod, which is specific to Chevrolet Small Block applications.

Is this pump for carbureted or EFI systems?
This pump is designed for carbureted fuel systems. It is not intended for EFI applications unless used as part of a properly engineered and regulated fuel system conversion.

Does this include mounting hardware?
No. Mounting hardware is not included and must be purchased separately.

What port size does this pump use?
The inlet and outlet ports feature 1/2-inch NPT threads for increased fuel flow capacity.

Does this include a gasket?
Yes. A mounting gasket is included for installation.
