if it's just end caps they're pretty easy to replace. make sure bleed valves were retightened correctly and no leak in any other part of the system. power purge to make sure the system is charged correctly.
as mentioned above, you can always do any modification you would like, but is it...
pump covers basically suck. should be ABS. had to clean and paint my F350s annually. replacing both on 2021 F300's (under YES, see my comments there). i would plan on replacing. good luck, ron
If it breaks it's worth it. if it doesn't it's not worth it. just like any other insurance. i get them for piece of mind and they kicked in a few times. good luck, ron
i believe engine placement is based on hull bottom and anti-vent plates positioning. your installer should be able to tell you were they need to be set.
belay the isolator comment. that pic looks like the grounds going to the isolator. you should still verify corrosion issues with them and the isolator itself.
yeah. galvanic isolators are a bit larger now as far as i know. you may not get the exact breaker, but they are available. agree that you need to verify the galvanic isolator aspect. ron
