Needed a way to test a 22re injector..this was my solution...I had an injector pigtail lying around. A 9 volt battery.. A rubber tire valve, with valve stem removed. I drilled a 5/64 hole in tip of cap, the small red tubing that comes with carb cleaner fits tight...
Then just give a spray of carb cleaner to get pressure, then tap wires to 9v battery
