If you are using OEM style, and you don't have patience that some the others do, here is what I did.

I cut the ends of the hoses, in the direction of the length of the hose, making the cut about 2-3 inches in lenght into the hose. This requires a set of heavy duty dykes or wire cutters to cut through the wire.

I then placed the end of the hose over the cap of a rattle to slightly spread the hose and to hold it into place at the wider position. This is basically near the same diameter as the factory hose fittings this will need to fit over. I then taped the end of the hose with quality friction tape (got mine a ACE HDWR), making the appearance near identical to what it did before the cut. This also helps hold it into position and from being able to expand wider an slip off.

Cut and install only one hose at a time. Install it quickly after removing from the rattle can. If not installed immediately, the hose will retract from the friction tape going back to its original diameter.

I found this to provide a tight enough fitment, without the frustration of forcing the fit. In appearance, it does not look obvious anything was altered, unless you really look closely. If done two trucks like this, and both have worked fine.
