need some advice, running 3/8" fuel line, how to run, what to use

that's tidy. The whole car too. The only thing some guys may tell you, and I'm only learning right now too, is that your fuel line can't run on the inside face of the subframe connector if you plan on racing at the track. NHRA rule I guess.

I'm going to install everything in the next day or so. I'm doing a street build, so just a mechanical fuel pump at the moment, and from what everyone says around here, a return line isn't necessary as we don't get the hot temps in Alberta. I did find a great part that just arrived today in the mail. I found an aluminium frame thru bulkhead (up to 3" so it should work), from Pure Choice motorsports part number 5910.

I got everything from anfittingsdirect.com. They are WAY cheaper than what I had to choose from around here. They definatly don't have the same diameter that the others do, but from what I've been told is they are decent lines.
