ice maker water tube too long

I bought a new ice maker. Water exits a tube from the top of the freezer and drops into a "funnel" on the ice maker. The funnel on the new icemaker is taller than the one on the old ice maker. There is no way to bend the tube up against the top, to be able to slide this new/taller unit in. Do I have to trim the tube? Or trim the funnel to OEM’s shorter height?
