Gas gauge calibration unit

The weather here turned cold, so I found time to get back to the project. I sent it off to Del 67Dart273 for testing with real gauges.

I am off to build a simple injector flow bench, with hopes of restoring few old injectors. I will start a new thread for my progress of "DYI injector cleaning and flow testing". It will be posted in the "Fuel and Air Systems" section of forum.
