    I am so frustrated could not locate the leak in the pump. When car is not running i dont see any leak once engine has stop you see oil in the floor after a couple of minutes .
    What could be the problem?

    Return line is the low pressure line. Usually regular rubber hose that typically is held to the back of the pump with a hose clamp. The pressure line will have a fitting attached to the hose and is screwed into the back of the pump. Certain applications will have two return lines, typical of many hydroboost systems.

    Return line would attach to the silver tube (with the black cap on). Pressure line would screw into the fitting just below that.

    I think its coming from the pump itself i saw a leak on the front. I will just replace the o ring. My problem now is what model of repair kit should i get ? The big rubber O ring is flat .
