Russ.....

That's exactly what I did. I had the same cap....bought a fitting....tapped it out and my buddy brazed the 2 air holes and also brazed the fitting to the cap and I used the Motive pressure tank. Worked like a charm !! I pumped it to 15psi and it held pressure so I know I had a closed system. When I opened the bleeder valve there was a blast of air that shot out and then a good fluid stream. The fitting I made up worked great. It's such a relief after 8 months of screwing with it. Life is good again !

Thx....Mike
