Upgrade Work:
Searched through most of Hab (eng area, in between lab and living area
level, GreenHab, eng storage area...) and located parts necessary to
assemble a hard diesel fuel line to a "T" and two valves for Wendy and
Casper (or other use). Planning on running off backup gen tomorrow as
well (will need to do oil change) to give opportunity to plumb lines
properly and investigate diesel leak in Wendy's prime tank.


Notes/Comments:
We obtained OneMeter readings using portable unit.
