Had this same problem on my 2000 XLS OHV. Line was split nearly the whole length. Wrapped it in e-tape for now, but curious about how I should go about replacing the line without kinking it or destroying the little green connector at the end. Any help is much appreciated.
Cut most of the way through the hose lengthwise a few times around the end next to the connector, heat it up and peel it off the connector. Wiggle a right angle pick in to get some room to grab the end of the hose with needle nose pliers right next to where you made one of the lengthwise cuts and start pulling down to rip the hose at the cut, then repeat for other cuts. First cutting the hose right after the connector might make it easier, or might not, a little hose still on it lets you grab the hose while you pull the cuts apart with pliers.
There are several videos on youtube about bending hose without it kinking, just get some bulk hose of the right diameter from the auto parts store.
This guy likes to use heat shrink tubing over it, but I am being lazy and linking the first video I found, knowing there are other methods without that, usually involving a heat gun and tubing bender, rapid cooling (ice water plunge) while bent, or filling the hose full of BBs or fine gravel, etc (
depending on hose diameter, very small hoses can have a length of stiff rope or string trimmer line put in them but be careful about not melting what you put in) instead of the tubing bender, plugging the ends if it's loose fill BBs/gravel/etc, so they keep it from collapsing then still heat/gun + cool down. If it wasn't an automotive vac, something like sand can work too. You don't want anything abrasive that can stay stuck in the tubing wall and come free later, possibly sugar would work then you can rinse it out.
Put some lube on the connector and heat the end of the new hose before trying to slide it in.
