So I noticed my coolant was draining quickly. I checked for a leak and noticed a small one between the two connections. Then I noticed it was the hose itself. I went to remove it from the rubber but when I did the plastic snapped like brittle bone. I was hoping someone knew this part number as mine is faded too badly and I did search but couldn't find it. Thanks.

Can't really tell from the pic but I think you need part #1

Yes, go to realoem...

looks like the plastic got impregnated with oil and broke (saw similar problem on a friends car, all the hose fittings were very brittle). check your coolant reservoir for signs of oil, also get your oil tested to see if there is coolant in it. oil filter housing gaskets are known to suck, might have a leak there.

Thanks for the input everyone. Found a local own parts dealer close by and got it new for 45$. BMW wanted 95$ lol I also replaced all the crappy cheap plastic line with one hose from the reservoir to the engine hose. Looks super clean and works perfect.
