Gas gauge calibration unit

Kit,
I will look for your injector tester. I built a pop-tester (2000 psig) for my diesel injectors w/ an electronic sensor and data recording. I hope to build a rig for my gas car injectors and will be interested to see your design. Most I have seen use a simple on-off switch, sometimes off a timer, and an array of graduated cylinders, though a single one should suffice. I expect your design will involve a microprocessor and perhaps an electonic level detector (pressure sensor).
