A new MKS pressure gauge was installed today on the FC-C3 tube section, on cross C7. 

FC gate valves, FCV7 & FCV8 were closed to isolate the C7 cross. The +x port angle valve remained closed, and a tee, gauge, and pump out port were installed. CF flange joints were helium leak checked, no signal found above detector background ~8E-10 Torr-l/s.

Volume was pumped to medium vacuum and volume remains isolated. Will need additional pumping and power/signal cables landed before joining with main FC volume.
