Well butofcourse it's never ez with an old S.
Started out well if not great with autozone having the hard lines,  
connectors and free use of a flare tool and bend tool.  I had decide  
to do the inner and outer lines since they were badly corroded from  
the back to the front as far as I could see.
After I got it all back together and started up, a new leak opened up  
in front ... In front of the trans support brace... whicih I hadn't  
even seen.
This was no doubt due to moving the old lines around when cutting and  
tightening and I didn't see these other corroded sections upfront.
So it's almost back to square one.
Oh, and of couse abou 3gals. Of fuel drained out when first pulled the  
lines out of the brackets .
Thanks for all the tips!
This is another of those not if, but when breakdowns.
And that's the way it is.
