Detailed Product Description

Autobest F9746M is intended for International truck and van applications that rely on a mechanical fuel pump rather than an electric unit. The threaded inlet and outlet design simplifies replacement on original-style fuel systems, while the cast construction supports dependable fuel delivery at the specified pressure range. If you are servicing an International AB120, C100, or L110, this pump provides a direct mechanical replacement path for the listed fitments.

Autobest’s Mechanical Fuel Pump line focuses on OE-style fuel delivery components for older vehicles and light-duty commercial platforms. The F9746M reflects that product line approach with application-specific fitment, threaded ports, and a gasket or seal included to support a proper service replacement. The F9746M part number should be matched carefully to the vehicle application before installation.

Common Issues This Part Can Address

• Low fuel pressure at the carburetor
• Fuel starvation during acceleration or load
• Hard starting caused by weak mechanical pumping action
• Fuel delivery loss from a worn diaphragm or internal wear
• Leaks at the pump body or connection points

Installation Notes and Tips

Verify the threaded 1/8-27 NPSF inlet and outlet connections before installation. Confirm the vehicle application against the listed fitment for your International model and year, and compare the original pump layout to the replacement unit. Clean the mounting surface and fuel line connections before installing the pump and gasket or seal.

For best results, inspect the fuel lines, tank pickup, and carburetor inlet for contamination or restriction before replacing the pump. The F9746M is a mechanical fuel pump, so it should be used on vehicles equipped for mechanical fuel delivery.
