Hey Andrew.
I am running the -8 an TFE line in the car and I can re-use that line. The -6an TFE is 0.32 ID and the fitting ID is less than that. Given that I will only have 4 fittings between the pump and the rail, I am thinking that this should be OK. I was set on running -8 until I started thinking about fuel heating etc. More fuel in the line, more to heat, right? Maybe a non-issue.

Probably so...my downfall. I think I can make the -8an TFE hose work, but I need to get some adapters to adapt the output of the Corvette regulator to -8an. a -6 to -6 female and a -6 to -8 male would do it.
I was on the aeroquip site and they have a chart that shows hose size required for a required GPM. According to their chart, a 255 LPH pump flowing full flow needs less than a 1/4" ID

If you aren't running boost, a -6 or 3/8 will be plenty, even with e85.
I 2nd the statement regarding the output of a single 255 walbro. it's a 5/16" hose barb.
The only benefit of running a 1/2" or -8 is the overall capacity of the entire line throughout the car. A restriction is a restriction is a restriction. The -8 will just give you more volume in the line before the injectors spit it all out. A -8 won't necessarily flow any more than a -6 from a single 255 pump.
My walbro 450 has a 3/8" outlet, but I'm running -8 line all the way to the rail.
