This is behind the driver's seat. It looks like he accessed it through a drain-cap thankfully and did not cut a hole in the floor:
The electrical tape is around the cap in the picture.
This looks like where the wiring harness was cut:
Another shot of the mech fuel pump. Hard to see because of the shady, green wire to the battery in the foreground, but there is one line in and one line out of the pump:
This shot shows the line running from the mech pump, under the water pump and block to the red/blue fitting in the picture. Fuel feed line I'm assuming:
This part got tough. Dead center in this pic, just under the firewall, the shiny part behind the power steering arm(?):
Another shot of the same part. I was practically mounting the radiator at this point:
One last shot of it. I'm assuming it's a regulator? The line to the pump, with the red/blue, fitting attaches here. Then heads under the car:
So from what I can see there is a line from the tank to the Holley blue pump in front of the rear axle. Then a line under the car to just under the firewall where that regulator(?) is in the last few pics. Then from there it goes to the red/blue fitting just in front of the engine block and then from there to the fuel pump. Then there is a separate line from the mech fuel pump on the block up and in between the block and engine accessories to the carb (pic below of the end).
