Update:
Well some of you know that this didn't fix the problem. It was worst than just the bleeder screw. The tank had a tiny hole in it and was leaking also. So I got the new tank today took 10 min to swap but now the hoses' quick clip do not fit anymore ....they are loose. Is this normal? Dealer tells me that new hoses will fix the problem.... True?
