Thank you all again. I had to go back with the plastic elbow, but I'm wondering if aluminum would make much of a difference - it was the O-rings that had allowed the leak, the elbow was intact. Dumb thing, though, the parts store guy says a local garage is ordering them all the time...

But I'm good an not leaking anymore, so thanks again all. FWIW, i was able to get 25 ft-lb on the larger bolts and 11 on the smaller
