OK, so did I REALLY need to do this? Probably not, but what the hell, why not?
Have always been chasing a fuel pressure issue, could never get a good 1 to 1 fuel pressure rise and this is what started this whole thing. After changing EVERYTHING except for the factory fuel lines and still not getting the pressure I wanted I decided to do the whole system over. Not here to listen to naysayers or you should drill out the stock lines etc, this is what I decided to do and just sharing.
Scored some new billet fuel rails and that is where I started. Also made a deal for a new Racetronix double pumper with the AN ends and braided lines. Using Fragola black anodized fittings along with their Teflon braided lines. Couldn't decide if I should dual feed the rails or single feed with one return to an external regulator. Figured I might as well go all the way so double feed was the way I went.
Stock fuel lines from the frame up to the rail along with the stock return were removed intact, quite a bit of work to get those suckers off. Running -8 from the tank up to the front of the car and then splitting to two lines to the rails in the front. Running the line along the driver's frame rail and up along the back of the inner fenderwell where it splits with a y fitting to the two feed lines.
Return lines are running along the driver's side of the intake manifold and down the front of the motor where the stock fuel lines ran to the Aeromotive regulator I mounted to the frame rail with a custom made bracket. The return goes thru the frame where the stock feed line was.
Now to make all this easier, I had already removed the EGR and all related parts. Also removed the vapor canister and the lines for that, going to run a vent off the tank in the back.
The billet rails make it necessary to raise the coil bracket as it now mounts to the top of the billet rail brackets. Raised it with some 1" spacers on the manifold, also have it tilting just a bit to so the spark plug wires clear the wiper arms.
I had previously done all my vacuum lines with braided hose so I had to reroute things a bit there but nothing too complicated. I have a mechanical fuel pressure gauge as well as a transducer that I use to log pressure, drilled and tapped the fuel log for the mechanical and the transducer is hooked up to the fuel pressure regulator.
Still playing around with the wiring in the motor compartment so just realize the early pictures are of a work in progress. Pretty busy around here so put in a few hours here and there on this project. Got all winter to finish.
I am using a fuel filter from Canton since I sell some of their products and they are in my back yard. I am mounting it on the underside of the trunk in front of the tank. Got a great product I am using to mount it without drilling any holes. Click Bond makes these great standoffs that uses aircraft type adhesive and special fixtures that hold everything in place while the adhesive cures. Got some pics included here. I bolted on the brackets for the filter and hung by them to put them to the test and they didn't budge. Have used these in the past on other projects.
So here is where things sit as of 1-21-13.

Any place the braided line might rub against something I have put wire conduit over. Hope to have motor compartment all done this coming weekend and then will work my way back to the rear of the car with final routing of the lines and wiring.
It was driven a lot though even from CT to PA for Super Chevy shows numerous times. And I don't miss having a Holley carb though I do miss the car.
Also, fuel gauge is pinned past full and I only have about 2-3 gallons in the tank.
Brand new double pumper setup, made sure the float wasn't hanging up on anything when I installed in the tank. Pumps went in fairly easy without forcing anything.
