Thank you for that information. I just bought the XP and it was not getting any fuel to the water seperator, I am changing all of the fuel lines as the "grey glue is everywhere :(
SBT sells a wrench that is bent with a 3/8 drive hole tp properly tighten that nut. It was $16 but I have found nothing is worth the frustration of not having the right tool and missing the skin for my knuckles!
