Brett,
    Sounds like a different setup from mine - rubber is not attached to
the block.  The short rubber piece is attached to a metal fitting
pressed into the block.  The tube is one piece and tapers into a smaller
diameter at the end.  Here is an attempt at some hieroglyphics -
probably won't unscramble correctly after transmission, but I tried. :-\


                                            hoses again -      = =

     \  -  tube smaller - about 45 degree bend towards passengers side

       ||    - tube going back into the plane of the screen

       ||___   - tube - 90 degree bend

            ||  - tube
                                                       BLOCK
  ||=   tube w/nipple (clamped off)

             []   - hose (very short)

           ||    - nipple (very short)

           (  )  - metal - connected to block (pressed in) with nipple
on top
