Joe, you won't be let on an nhra track with the regulator mounted on your firewall. Its a big no-no to them. You also might have issues with those lines looping over the tank, being gravity fed.
I did alot of research on the lines over the tank and the Walbro pumps are real good at drawing fuel so that should not be an issue. Did nto know about the firewall thing though. Not moving it because then I have to fix the holes. Oh well.
Very nice! I was able to knock out my return setup in a couple of weekends. I didn't go with a sump setup though. I used the Fiore hat that goes in the stock tank.
