Success for the first round of maintenance. Replaced coolant, transimission oil, fuel filters, clean out the banjo bolt and vaccum line. Also replaced several rubber vaccum fittings as a preventative measure. The car starts on the first crank. No more smoke. The brake system seems weak. Will investigate and correct it before doing extensive test drive.

One question I have regarding the spin on fuel filter:
Fuel is sipping pass the big 22mm bolt head. I tightened it some more and it seems to reduce it quite a bit. I searched the topic and found one thread about it. Is there a final word about the sealing O-ring, metal sealing ring and torque spec?
I don't feel comfortable with all the torque applied with the big 22mm wrench.

Yes sometimes it takes uncomfortable levels of torque to seal it, not a bad idea to just buy new seal rings for it.
