The install was easy enough, finding a t-piece in work was the hard bit. It's connected to the brake vacuum hose at the manifold and the line going to the gauge is a length of 3mm pneumatic hose. I had to change the response time of the gauge to the slowest setting as it was jumping like a mad thing. Not by huge amounts now, just by a few inches but it was flashing too much so i slowed it down and now it's okay. It holds its memory when powered down so that's nice!

Your idle is great. It's on the high side of were it should be. Did you get that one off the machine you were telling us about? It looks good, I hope you save many gallons with it!
