Last year I bought a rear mount apex. This summer I stripped it down to go through evrerthing and prep it for this season. I noticed the intake tube that comes from the pre-cooler in the tunnel goes in where the tank is and then proceeds through the gap between the frame and the top of the engine (over the oil fill cap). The rubber tube seems to be quite flat and squished. Is this the correct routing? Seemd inefficient. Thanks for any advice.
