June 8, 2010 - The fuel system is done!
It looks pretty nasty in this picture, partly due to the random wires of various sizes floating around and also due to some weird angles. The angles were chosen so I could use 45 degree fittings instead of 90 degree for less restriction. I also had to squeeze all the components into a fairly small space, of course.
The fuel comes from the tank through the 3/8" feed line, the leftmost one at the top of the picture. It's then adapted up to 1/2", because that's the size of the inlet on the pump. I didn't use 1/2" for that entire stretch because the actual line coming out of the tank is probably 5/16". The fuel then runs to the Corvette fuel filter, which doubles as a regulator. The braided stainless line at the bottom is a -6 AN line (3/8") that runs all the way up to the engine. The return line runs back to the tank through the factory swirl pot mystery cylinder at the moment. The stainless feed line runs through the transmission tunnel and is well anchored to keep it safe and to keep it from sawing through other things.
It took a remarkably long time to get all this done. Not only did I keep having to source adapters, but even securing the stainless line involved crawling under the car, measuring for a hole, drilling from above, crawling underneath to check the location, crawling back out to tack-weld the bolt into the hole, then going back under to bolt it up. Then move on to the next spot and do it again. Add to that the usual "whoops, I left my pen/ruler/wrench/fitting/drill on the table" up and down routine, and it seems as if I spent most of my day simply going under the car and back out again!
