RPM Air Gap water hose question

Sorry to say the first problem is also the answer and that would be the pipe used off the intake is to long and needs to be replaced by a more factory styled short pipe. I do not know why Edelbrock puts that thing in the box for use.

You need an intake manifold pipe only approx. a 1/2 - 3/4 inch long off the intake. Just enough to use a clamp to hold the hose on.
Cut that brass one down a good bit.
