Review on ALLOSUN EM276 Fuel Injector Tester by Jeremy Choi

Note on the electrical connection at the injector: I found that I could use two small alligator clips to grab the tiny connectors by clipping one side of the type clip placed "crocodile" inside the plug (side) and the other side outside the plug. This worked on one out of four injectors. It worked for part no. VW 06H906036P but not for VW 06H906036E and Bosch 06H906036AB. This makes a clicking noise, but it is pressurized fuel from the throttle body and air intake cleaner (outside the vehicle). Even the small 9V battery didn't work. However, the Prius HV battery module at about 6 volts was leaking fuel. That's a good idea. I think the fuel injector needs more amps. I've found that using flexible hoses, spare parts from the vacuum test kit, and clamps work well enough to test.
