I was going to do that. The hose is a real piece of garbage. WE'll not the
hose itself but they way itt attaches in the rear. On the pcv valve there is
a rubber piece of hose that slips over it and the pcv valve. Niether one
will budge. At the rear of the intake it uses a piece of foam tubing. I
think the idea of a solid plastic hose is ok, except the fact that since you
have to rotate the pcv valve to get it out it will not allow you to do it,
but using a piece of foam rubber hose is not. All they do is expand and
never contract. Anyways i'm going out now to see what I can do.
