Air Intake Hose

[Sintonics]

Got an '04 SE7. I recently installed a Raised air intake by Mantec. There is a hose that connects from the bottom right of the air box to the inside wall that connects to the air intake. Weird material, and was totally rotten. I cannot find this hose or a better replacement. I've looked online at diagrams that show the hose but doesn't list it. and it has a weird almost rounded off rectangular shape to it. I've been to hardware stores, Plumbing warehouses, home depot, Ebay, online parts, even boat yards. I cannot find a hose that will fit properly enough to water proof. So I have a new raised air intake not doing anything but looking pretty.
