Muckman I've been debating what fuel setup to go with. I really don't want to get a fuel cell or sump my tank, I been debating whether to get the Walbro 450, Or get a full blown motorsports dual pump hanger, and run dual walbro 255. If I needed more fuel after that i'd upgrade for dual 340's which would be capable of quite a bit I think.
My last setup i've researched which will cost $1000 total. Full blown motorsports dual pump hanger, -10 feed, -8 return (That way I don't have to upgrade ever again), Another walbro 255, Which will run to my current aeromotive filter and fuel rail. So in the end I would have, Full blown dual walbro 255, -10 stainless feed line, -8 stainless return line, BDL fuel rail, fiveo 1600cc injectors, aeromotive filter inline before rail on feed, Than a aeromotive or weld-on fuel pressure regulator (Got to do more research on regulators), I think that setup would do what I need and it wouldn't break the bank as if I would have got a fuel cell, sumped the tank, etc.
The reason I was looking at the dual pump hanger over the single walbro 450, Was I would have to modify my stock hanger for the bigger feed and return lines, If I get the full blown hanger that takes the guess work and welding etc out of it. I don't have a welder and have to pay someone to do that, Buy all the fittings, etc. I think the full blown hanger is a better alternative because it comes with AN fittings already in it and I can just get 2 more fittings and install fuel lines no problems.
