one more successful transplant on this, and echoing what others have said here. no need to dismantle anything. i think the hardest part was getting the new sensor positioned where it needs to be.. it's a bit of a ship in a bottle building game. i ended up also using something like a coat hanger to drop the sensor in from the fender side, and then hook onto the bolt hole and pull and rotate up.

interestinly I had the same torn o-ring as CamasM3e93. sensor has original date code so i don't think it's been off before, and the tear definitely looks like it was from being screwed on, not from removal (the excess rubber is up the connector, not down). wonder if that's just expected?

either way, doing this resolved by vacuum pump running issues. went from running on every brake pedal press to only briefly on startup.
