After first decoupling the 3/8" tubing at the top of the CP3 vacuum vessel, we fed SS wire into the obstructed 1/4" level sensing tube.  We were able to feed enough wire as to think that we were within 1 foot of where the tube connects with the inner LN2 reservoir -> We then remove the wire and coupled the 3/8" line 

For tonight, we are leaving the two sensing lines combined at the 3-valve valve body via opening the valve which normally isolates the two.
