Today we decoupled both ends of the external 3/8 tubing used to sense the liquid pressure sampled at the bottom of CP3's inner LN2 vessel -> We then blew through it with bottled UHP N2 to verify that it wasn't the source of obstruction -> Next, we reconnected the end at the vacuum interface and pressurized the tubing to 15-20 psi in an attempt to "blow" the obstruction back into the liquid vessel.  We also tried "pumping" the line to rough vacuum -> A second attempt at pressurizing it, this time to 30 psi, did not dislodge the obstruction

1500 hrs. local -> Manually overfilled CP3 via the LLCV bypass circuit (liquid exiting exhaust line) 

We will manually top off pump periodically until issue is resolved -> The LLCV is in manual mode at a constant 15% open (recent average prior to problem was ~19% open)
