Hope no one minds me sharing, but this is my article for AmericaSpace on the 29 March EVA.

Feustel/Arnold are setting up communications hardware for ECOSTRESS and C2V2 architecture.

ISS Daily Summary Report – 3/19/2018
EVA Tool Gather and Configuration: The crew gathered and configured tools and hardware for US Extravehicular Activity (EVA) 49: N3 Enhanced Wireless Communication (EWC) & Camera Port (CP) 8 and US EVA 50: Pump Flow and Control Subsystem (PFCS) Relocate.
Do we have a specific date for US EVA 50?
The question is, which PFCS they will relocate. The new one , which will go in the SpX-14 trunk to the ISS, or the used one, which will go down in SpX-14.

MEDIA ADVISORY M18-047
NASA to Preview Upcoming US Spacewalk, Provide Live Coverage

Two American astronauts will venture outside the International Space Station on Thursday, March 29, for a planned 6.5-hour spacewalk. Experts from NASA will preview this work in a briefing at 2 p.m. EDT Tuesday, March 27, at NASA’s Johnson Space Center in Houston.

Live coverage of the briefing and spacewalk will air on NASA Television and the agency’s website.

Participants in the March 27 briefing are:

    Kenneth Todd, International Space Station Operations integration manager
    Anthony Vareha, spacewalk flight director
    Grant Slusser, U.S. spacewalk 49 officer

Media who would like to participate in person must request credentials from the Johnson newsroom at 281-483-5111 no later than 4 p.m. Monday, March 26. Media interested in participating by phone must contact the newsroom by 1:45 p.m. on the day of the briefing.

Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold will don spacesuits and exit the station’s Quest airlock about 8:10 a.m. March 29 to begin the 209th spacewalk in support of space station assembly, maintenance and upgrades. The excursion will be the seventh in Feustel’s career and the third for Arnold.

They will install wireless communications equipment on the station’s Tranquility module to enhance payload data processing for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) experiment being flown to the station on a future SpaceX Dragon cargo spacecraft. The experiment will measure the temperature of plants on Earth to better understand how much water they need and how they respond to stress.

The crew members also will swap out high-definition video cameras on the port truss of the station’s backbone and remove aging hoses from a cooling component on the station’s truss.

ISS Daily Summary Report – 3/26/2018
 

Extravehicular Activity (EVA) Preparations:  Today the crew will continued preparations for US EVA #49 – Node 3 External Wireless Communications (EWC) installation, planned for Thursday March 29, 2018.  The crew continued with EVA tool configuration, reviewed on-board training material for fluid Quick Disconnects (QDs), reviewed EVA translation paths using Dynamic Onboard Ubiquitous Graphics (DOUG), and reviewed EVA procedures.  At the end of the day, the crew had a conference with ground EVA specialists in order to discuss any question on the activities they performed today or will perform during the upcoming EVA.

ISS Daily Summary Report – 3/27/2018
 

Extravehicular Activity (EVA) Preparations:  Today the crew continued preparing for US EVA #49 – Node 3 External Wireless Communications (EWC) installation, planned for Thursday March 29, 2018. They completed additional Airlock and Extravehicular Mobility Unit (EMU) configuration and performed an EMU Water Tank and Liquid Cooling Ventilation Garment (LVCG) Water Fill.

Television Camera Interface Converter (TVCIC) Fastener Remove and Replace (R&R): Today two crewmembers R&Rd the three life-limited TVCIC fasteners that secure the unit to the Video Stanchion Support Assembly (VSSA). This TVCIC is required for the External Television Camera Group (ETVCG) scheduled to be installed during Thursday’s EVA.

Also this from last week:

ISS Daily Summary Report – 3/21/2018

Radiator Beam Valve Module (RBVM) Reposition: Today ground specialists repositioned the RBVM P1-3-2 from the Closed to Vent position in order to purge any remaining ammonia in the P1-3-2 Radiator flow path in preparation for next week’s US EVA 49. The P1-3-2 RBVM supply and return jumpers are tasked to be removed during the EVA and brought inside ISS for future return to Earth.

That was the hardware that is the suspected location of the small ammonia leak in the thermal loops which had been isolated with the RELL (Robotic External Leak Locator) and previous EVA operations.

The question is, which PFCS they will relocate. The new one , which will go in the SpX-14 trunk to the ISS, or the used one, which will go down in SpX-14.

According to Ben E's article for AmericaSpace, one of the potential get aheads for EVA-49 would be to, "break torque on bolts on a spare pump module on External Stowage Platform (ESP)-2 and a flex-hose rotary coupler on the S-1 truss. 'This would economize time for these tasks,' Mr. Navias told AmericaSpace on Monday, 'for R&R work in the future.'” 

The recent NAC meetings had an ISS update with a slide for the upcoming EVAs and a planned use update which showed the EVA-50 as currently being in mid-May.  From the description, it sounds like the EVA is just swapping the location of 2 PFCSes that are both currently being stored, which seems somewhat silly to me.  But maybe I'm reading that wrong.
