I need to plumb my two fuel rails on my 20b.  originally it must have had rubber hose connecting them.  should I run rigid lines? AL or steel? 
 
I used the same braided line that I used for fuel everywhere else, but with double hose clamps on the ends that had hose nipples rather than AN fittings.  I made a list of ID measurements of AN hose that helped me pick the proper size for these situations.  Here it is:
 

AN hose ID

AN-4 = 3/16”

AN-6 = 9/32”

AN-8 = 13/32”

AN-10 = ½”

AN-12 = 19/32”

AN-16 = 13/16”

 
 
   I guess I'll have a braided line from the firewall to the first rail, with the pump behind the firewall somewhere, and another braided line for the return.  somewhere I need to insert a fuel pressure regulator, since I sawed off the one I had thinking it was something else (duh).  will it need to be in the engine compartment?

I put mine inside the cockpit, where the pumps are.  You can see it in the photo (the red thing).
