Trying to figure out if the Garmin PN: 010-00705-64 GHP 1.2L Pump is adequate for my 2002 Carver 346 autopilot upgrade.

Backstory: Bought a low hour (220) freshwater Carver 346 (2002) last season, this year embarking on a major Garmin upgrade of all systems they touch (MFD, sonar, radar, autopilot, stereo, VHF, lighting). Launch is scheduled for week after next. Just finished sanding entire bottom, next is a fresh coat of Hawk Monterey bottom paint, installed new magnesium anodes (1.5" shaft, R4 trim tabs, 6" transom), washed hull ready for polish and wax, have some questions about the autopilot pump to use. Looking for any experiences here with similar Carvers (346, 366, etc). This is Garmin list at the moment:

MFD SONAR: 1243xsv 12" GPSMAP X3 series with UHD SideVu sonar through hull transducer
RADAR: 18" Fantom
AUTOPILOT: GHP Reactor 40, considering 1.2L Pump Kit PN: 010-00705-64
AUDIO: Apollo MS-RA770, still figuring out all the speakers and zones (aft cabin, lower salon, aft salon/bridge, swim platform)
COMMUNICATION: VHF 215 (fill the hole in the dash)
LIGHTING: TBD, so many options, want a system I can build off over a few years
OTHER: Starlink Mini, Seaview 5" pedestal on arch, polished SS chain/anchor
FUTURE: bow thruster

Appreciate any comments on pump and other items based on your experiences.
