I am researching options for fuel pump/tank for my upcoming LS3 conversion, and have done some searches. There seems to be a bit of conflicting info regarding the return fuel line... 1. If I run an in-tank pump, is a return line necessary (or desireable)? 2. I was thinking of copying this technique: http://www.cardomain.com/ride/2532279/2 using a new Goodmark tank, but then I ran across this: http://www.paddockparts.com/Paddock...Fuel&mscssid=AE743029284849C3B5E79B5349C89C9A which seems like a pretty good deal, about $600 complete, which isn't all that much more than it would be for a new tank, pump, etc. The only thing that concerns me is that they don't seem to mention any baffling inside the tank. Anyone have any experience with these tanks?
