G'day scottya! Nice project you have here, it may be controversial to some people, but I reckon it's pretty damn tough!
I'm curious about your fuel system... I stumbled over this pic below... can you explain how it's setup. Obviously you're running a return line... is this a standard type of reg? Is the fuel inlet going into the reg, or the rear of your fuel rail? It's different to anything I've seen before... just trying to work out which way it flows, and where the bypass pressure bleeds off... it almost looks like a return-log style setup??
Anyway mate, keep up the good work!
