Fuel return line size.
Dont think I am reposting since I cant find my previous one (moderators ?) , anyway , I finally got my twin Bosch '044 pumps installed and will be starting up tomorrow (after I get my 180 deg fittings) , I was told that those pumps would cause an idle pressure of about 60 psi with the stock return line , can anyon say if this is so or not ?.

It depends on your feed size?
As a rule of thumb, you go down one AN size versus the feed size.
-8AN feed, -6AN return
-10AN feed, -8AN return
