Lol's thanks guys! They replaced the lines that touch the carbs but nothing else, adding inline filters to the line-in and returns. As a seadoo n00b it's taken me a little to see through the mistakes. I've replaced all the lines and will do these as well, eliminating the inline filters.
I'm guessing she'll run better? Could these added filters cause carb tuning issues?
On a side note, I finally got to ride it this weekend and she rips, but requires the fuel selector to be on res, will clean the selector or replace before the next ride.
This was my first ride on an xp800. Holy shit, WAY WAY faster than I had expected. So happy!
