I have a fast 2.0 in mine w/ an external pump and return lines. has worked very well so far. I put a new tank in, w/ 1/2" (hex shaped) pipe caps that I cut the end off of in my lathe, and had a real welder weld the on the bottom corners of the new tank. then just drove a tapered sharp punch in thru the open caps to where the holes were the same size as the caps. came out w/ dual shut off valves-then to dual 1/2" inline filters, then thru a y, and in to the pump. thru the frame and subframe connectors to the front where the pressure reg. and other f.i. stuff is mounted on the fender. the return goes back and ties in to the original tank 3/8 fuel nipple, w/ the sock cut off . the fuel gauge is a little slow, but appears to work correctly. easier than it sounds, but a little time consuming.--------bob
