A vendor reported an issue with one of the mechanical gauges at CP3, the problem was verified and the quick solution was to swap gauges with CP4 (this tank is not being used at the moment).

First I cleaned the large 6 inch dial gauge, debris and dead bugs were removed, but after some water revealed a leak on the 2.5 inch gauge threaded connection I opted to swap the entire assembly.  The leak might turn out to be a source of noise on our read back channel.

The gauge pair from CP4 was removed and installed on CP3, all connections were torqued and valves returned to their normal position, had to close the liquid side shut-off valve for both tanks.  The gauge pair removed from CP3 was installed on CP4.  No issues were encountered during procedure, aside from the snow and the leak.

Work done under WP#8124.
