He Made His Own Fuel Injector Tester
“My homemade fuel injector tester works great for trouble shooting injector problems on diesel engines,” says Paul Bernier, Geyserville, Calif.
  He made a tester out of a hydraulic jack from a cab-over truck.
  “The jack normally lifts the cab to gain access to the engine. I found that it produces 2,500 psi, which is enough to pop the injector and check the spray pattern,” says Bernier. “I had to add a pressure gauge, adapt the hydraulic line to the injector fittings, fill the reservoir with diesel, and bleed the line. I watch the gauge while pumping the handle, which lets me see what pressure the injector pops at. The spray pattern is easy to see. It has saved me a lot of time diagnosing problems.”
