i wonder if anyone has any tip/tricks to getting this hose off?, ive pulled the metal clip out, and put my hand round the left side off the engine round the manifold shield to get a good grip on the pipe in question, but it just wont budge, kind of typical that a "quick Release" pipe is takeing the lognest to disconnect anyone else had this issue? how did you get it off? any help would be apreciated, thanks, diagram included so u can see what im on about

 

ive been at this for hours now, still at a loss as to what to do, the quick release pipe just wont budge, i can see it wiggling about on the flange ever so slightly when i pull and twist the hose, but it just wont come off!!! help!! can i spray some wd-40 round the outside off the coupling? or will tht damage to pipe, i remeber somthing about oil and water pipes not being a good combination as it soaks into the rubber or somthing. realy need to get this pipe off so i can take the flange out, but seems impossible.
