Thanks again bill. It is surprising how you seem to have detailed information on most any topic that arises. I guess spending more than 10 years maintaining systems in an organized fashion does that.
The pictures sent by Barry of Amel #016 that just had their systems serviced in Hyeres seems to suggest that we have the original connector/manifold installed on our 54. As you indicated, I think I tightened too much in order to get the gauge in the proper position and ended up stripping the threads. I do have and use JBWeld but since we are back in States for a few months, wanted a permanent solution. I do have an e-mail to Maude at Amel and waiting for her response.
Hoping that you will continue to contribute to this great forum in the future.
