Product Details

Description

Built for carbureted Chevy small block V8 applications, this mechanical fuel pump supports dependable fuel delivery with a clean engine-bay appearance. The 80 GPH flow rating and 6 PSI operating pressure make it a practical choice for replacement and upgraded fuel systems where the engine uses the correct mechanical pump mounting pattern.

Fuel Delivery & Pressure Control
The mechanical pump design is intended to supply steady fuel volume without requiring an external electric pump. Its 80 GPH rating helps support consistent carburetor fuel supply while the 6 PSI pressure specification keeps the setup aligned with typical carbureted requirements.

Material & Finish
The aluminum housing uses a chrome finish for a clean underhood look while helping maintain durability around engine heat, vibration, and fuel-system service.

Connection & Installation Details
Threaded inlet and outlet sizing of 0.250 in. NPT and 0.250 in. NPT help simplify line matching during installation. Verify pump arm style, gasket placement, pushrod requirements where applicable, line routing, and clearance before installation.

System Matching
Use this pump with compatible carbureted gasoline fuel systems and confirm fuel pressure, line size, and flow demand before installation. It is not intended to replace an EFI pump unless the full fuel system has been properly converted and regulated.
