Correct. On my car it's a plastic hose, not rubber. ~8mm O.D.
It is connected to the intake mfld via a short(~40mm) rubber reducer.
Cut the hose before the check valve wherever you feel suitable.
Make sure that the plastic gasoline filter does not touch either the WG or the 
back of the head or bell housing otherwise it will melt.

Watch the direction too. You want to connect the mfld side to the spout that 
goes to the bottom of the fuel filter (usually the central one) as to let the 
oil precipitate on the bottom. The pick up spout should be the one from the top 
of fuel filter. It should be connected to the A/C programmer.
