Thanks, jim.  I have been looking for spots of leakage and found none...but
you are right, I try to bleed and get what I can and then two days later I
check it and low, so added and did not have a chance to bleed.  Gotta
believe I lost more than I thought in the new hose replacement.  Not gonna
drive to Couprus Christi tomoorw in it due to this concern(funeral :-(
BTW-I always appreciate your help. Have a good one.
