Not something I did to my Reatta but something I did for my car. I related I had misplaced my pump and accumulator test gauge setup, and it is still missing, but I constructed a new one today. I found it very difficult to find conversion adapters locally, both bubble flare and inverted flare to npt for the tee and gauge. I had to resort to ordering them via the internet which was time consuming. Even NAPA had nothing, which was a surprise b,ut all fixed now. Dave and I will be testing a few accumulators in the near future.
