I would bet by looking at the packaging that the insurance won't cover the bad packaging job. Been there.
If you try, and they do cover the damage, they don't give the unit back to you. Been there also.
Will the seller back it? I would hope so. As far as repair, I believe that you could send back to MRC and they will repair for a fee.
If it helps, I have a Panworld PS200 and a Sequence Uno Wahoo sitting around. The Wahoo needs new seals.
I also have a brand new Dart pump collecting dust.
PM if at all interested.
