Description

Maintain consistent internal injection pressures and prevent fuel system failure with the Thermo King Genuine OEM Fuel Injection Pump Spring Assembly (Part 118973). Available in a bulk-savings pack of 10, these factory-original internal springs work directly alongside the metering valves to ensure steady tension and precise fuel return cycles. Manufactured in Japan to extreme tolerances, these springs prevent fuel starvation, engine lag, and unexpected shutdowns in overworked reefer engines. Keeping this 10-pack on hand ensures fleet operators and mobile mechanics can easily swap worn springs during high-volume injection pump overhauls.
