EFI Fuel Lines
Here is how I decided to handle the fuel lines. I am using the old line as the return and will run a new feed line next to it. The -6AN bulkhead connectors mounted in brackets on the frame and the head will be connected with braided hose. I will be running hardlines from the head bracket to the EFI feed and return.

Running fuel lines with the body off is soooo much easier. I did mine with the body on and it was a major PITA. I like the bracket with the fitting on it. I just put a hard tube adapter on the hard line when it got to the engine bay and then ran the braided up to the fuel rail. Yours looks much nicer than mine.

VetteNut72-Nice job on everything, not just the lines. Are you going to use a pre-formed line for your fuel line (and return)? Are those Russell fittings?
Scooter70- Is running a pre-formed line with the body on difficult even with the trailing arms off?

Scooter70: I had the car running after installing the injection but the return line was too small causing multiple problems. I pulled the body just to run lines and decided to do the frame off after I saw what was under the body! 
A friend of mine fabricated the brackets for me from 2" angle iron.
BBShark: Thanks, I'm using the original, pre-formed steel line for the return line and running an aluminum 3/8" line for the feed. Yes, the line ends are from Russell.

NO, I would not use aluminum, it's a bad reputation for doing strange things under vibration, it's likely to rub a hole in it, too soft, and maybe even shatter at a flex point....had it happen on a boat once, wasn't a fuel line, but do with steel.....
OH, what were some of the original operational problems this was to cure, and did it work???

The trailing arm wasn't a problem as much as going from the side rail up the kick-up for the rear suspension. It's a hard pretty corner and requires some flexability when doing it from underneath.

I agree that if it isn't delt with properly, it can be a problem. I believe that by terminating each end into bulkhead fittings mounted in a bracket attached to the frame, as well as using rubber insulated clamps and carefull routing of the line, it will work well for my application. I built single engine aircraft for Cessna in the 70's and aluminum line was used extensively. I agree that you cant let it flex or rub on anything.
The car was running very rich and the computer could not compensate. If the excess fuel cannot be released via the fuel rail regulator, then the fuel rails exceed the normal operating pressure causing more fuel to get through during each injector pulse. I was using a small (original return) line that restricted the ability of the regulator to release the excess pressure.
