2002 polaris rmk800 help!

I went up sledding after having this sled out of an unmentioned shop and had to stop because of the new oil cable re routed to close to the twin pipes and had a cable melt down which of coarse has its own set of problems. I also noticed that one of the oil lines was off at the oil pump. We limped the sled back to the truck but kept an eye on the oil line and noticed that it kept popping off. I tried to blow into the line to see if it was obstructed and could not get it to flow. I tried also with the line off the machine and there was not any obstruction in the line itself but it would not blow through the injector on the carburator. Then I tried on the other carb and it would not work as well. Sorry about all of the words but just trying to figure out if both carbs are blocked as they appear to be or is there some kind of baffle stopping the flow as part of its function. Hope this makes sense.
Any help would be appreciated

Oil pump

The fittings at the carbs are actually check valves. I don't think you can blow through them. Takes more ump than that. A disposable syringe from your local pharmacy will allow you to put enough pressure on the line to overcome the check valve. Fill it with injector oil and plug it into the line at the pump. You should be able to push oil with a little effort. Air compressor would work too a low setting. If not then the check valve may be stuck. Sometimes this can be fixed by squirting then with brake cleaner and letting them soak a little. Also a little heat sometimes works like from a soldering iron.
As for the lines coming off the pump, there is pressure there and if the fitting is plugged then it may pop off. If fitting is open then it may just be the line is stretched and not holding on the pump tight. There should also be a small clamp on each line as well to help hold them on.

Check the 2 on the crank as well.

Thanks, for the info. I will try the syringe then use the brake cleaner. Hoses and clamps seem to be ok but I may replace just to make sure there isn't a future problem.
