  1. #1
    hey, i have a problem with my saxo mk2 1.1, the pipe that goes to the back washer jet leaks inside the car causing a puddle, i know it is this because when i drain the bottle the leak dries up....

    so i want to know if it is possible to remove the pipe when i dewiper the back( what size grommit do i need?

    , and also which pipe coming out from the washer bottle is the one to the back; isit the furthermost pipe or the one nearer the back?

    thanks for any help
