  • J-47912 Fuel System Priming Pump
This Oni Tools fuel system priming pump is a solid alternative to the OEM and OTC versions for Detroit Diesel engines like the DD13, DD15, and Series 60. The stainless-steel tank feels sturdy and well-built, with smooth welds and solid fittings that hold up well in shop use. The included gauge, quick-connect fittings, and long hose make it easy to purge air and pressurize the fuel system after a filter change or repair. It saves time and frustration when starting up a diesel after service — a real must-have for anyone who works regularly on heavy-duty Detroit engines. The unit is simple to use once you understand the connections, but it’s definitely designed for professional mechanics more than casual DIYers. The tank and pump are a bit bulky to store, and it’s not exactly cheap, but the reliability and build quality justify the price if you’re using it often. professional-grade quality, solid construction, and dependable results. If you service diesel fleets or Detroit engines regularly, this will pay for itself fast. ... show more

  • Worth the money
We purchased this for our shop and it works great. We have used it maybe 20 time and it has not let us down. The pump handle is ok but has a place to use an air chuck, much faster.

  • J-47912 Priming Pump
The Oni Tools J-47912 fuel system priming pump is a smart buy if you work on heavy-duty trucks with Detroit Diesel engines (S60, MBE 900, MBE 4000, DD13, DD15). It’s effectively an alternate to the OTC 5869 tool, but at a lower cost. The build quality is solid—metal fittings, a clear hose that helps you see air bubbles, and a robust handle for manual pumping. It helps you prime the fuel system before starting after service, which is critical for these modern high-pressure diesels. Using it saved time and prevented the frustration of air in the system causing no-starts. The clear hose allowed me to monitor the flow and confirm the fuel was moving properly. It fit into the tooling routine nicely, and I felt confident using it on a shop-level service. The only minor issue: it takes a little patience to pump until all air is purged, and sometimes you need to position the truck slightly differently to reach the fuel line. But that’s usual for any priming job. Overall practical, well-made tool for diesel mechanics. If you service Detroit Diesel engines regularly, this pump is a cost-effective alternative that still does the job. ... show more
