Pretty sure its the high pressure line fitting at the top, 17mm bolt if I remember, I assume its the coppers crush washer thats the problem.
Is this a part that I can just get at the parts store for my truck or will I need to know the size and order one that way ?
I will totally clean and make sure its not the hose when I can.
