    Hydro boost leak ugh

    Last time I had my mustang out it sprung a leak in the hydro boost.   PS pump got hot so I replaced it.  I had a little time yesterday and investigated the leak.  The block that bolts to the side was leaking.  It was tight and the o-rings appeared to be in good working order.  I replaced both the LP ring and put a slightly thicker o-ring on the high pressure port.  Haven't driven it but no leaks idling in the garage.
