ESOC-250E
Fuel Priming Pump Tool S60
Detroit Diesel

Designed for workshop use in the fuel system service category (VMRS 044-003-222), this electrical priming tool is powered by 110 VAC and provides a controlled priming flow to the low-pressure side of the fuel circuit. In service scenarios, after component replacement or line bleeding, it pushes fuel through the priming line to purge air, verify integrity, and prime the pump internals before high-pressure delivery. Benefits include faster, smoother engine startup after service, minimized crank cycles, and reduced wear on the starter and injection pump by eliminating dry starts. The tool's electrical interface supports common shop outlets, enabling quick setup and mobility around the service bay. Compatible with engine families and hard-to-prime installations in Detroit Diesel platforms, the device belongs to the engine support tooling subset (category_id 53458), ensuring traceability within the approved diagnostic and maintenance tooling catalog. Practical applications span in-field maintenance at customer sites and fixed shop bays, especially after fuel system maintenance such as filter changes, line bleeding, or injector service. The compact design and 110-volt operation offer a reliable priming solution during both routine servicing and emergency start attempts. Note the safety warning in the product literature regarding cancer and reproductive harm; follow all PPE and handling guidelines when powering and operating electrical tools.
