I had hoped I could come up with a plan to do this install easily but to do a nice job will take a lot more work.
I've installed and plumbed the fuel pump & filters and today I worked on this little art project.

Image
This line (new high pressure supply ) basically follows the same path along the pinch weld under the car that the fuel line on the other side does and ends up going into the eng bay the same way through the fender well liner.

I'll work up a post to show all the components when I get the remaining parts I need.

Any concerns over body flex regarding the supply-side line as you have to avoid the flexible rubber joints like on the OEM side?

(Oh, yeah, and dangle all the participles ya want. I could care less but, watch out for Steve; he's a bear!)

Not really, The front corner is overlapped by the sub frame so it's stiff and the line will have plenty of length along the bottom and the eng side line (of which I'm changing the routing from the pic) will go all the way up to the underside of the cowl,
Between those two long runs it would have plenty of room to twist during slaloming events.
I always figured Ford made that line in multiple pieces for ease of assembly anyway. I started having a heck of a time once I tried threading it into the eng bay.

I'm going to rework the eng end to get rid of one 90 degree bend and replace the last couple of bends that started to colapse the tubing.
I used a hand held bender for the back and one of those spring benders for the front. The spring thing is good for a bend of less than 45 degrees or a large arc but it's no good for a sharp bend.

Here's a comparison of the bend quality between the two devices:

Tubing benders better (oh that felt good).

Yeah, maybe good for line installers; sux for us. That hidden 5" rubber under the front fender is one of the worst things on the car.

Nice having a tube bender for this work.

Bit of a setback today. My original plan was to use the gas tank drain fitting for the return line but after looking closer, that isn't the best way to go. While it's technically feasible, I would have to make a metal line that would run very close to the exhaust. A rubber line would cook and the routing just isn't good.
So I dropped the tank (took 30 minutes) and will drill a hole next to the existing sending unit. I'll use the existing fuel line as the return line and simply move the existing short rubber line that now goes to the tank supply to this new port. I wont have to change any hard lines in back or even the rubber one. The only new hard lines I'll have to make is for the entirely new supply line.
So the nearly new tank is out again and full of water and degreaser. After it soaks overnight, I'll drain, rinse and refill with water so I can drill the tank.
Having the tank out also gives me great access for mounting the EFI fuel pump and will make the whole job easier.

This is the part of the mod that has had me running scared. Once I drop the tank on my car, there will be rust to fix--and I don't know how deep that rabbit-hole-mission-creep goes.

Is there any reason you didn't route the new line alongside the old? Would love a photo of the clips you'll be using to hold the new line in place.

I am seriously considering cutting the orig line back a few inches and grafting on a new piece of solid line up to the EFI.

Do you mean rust in the tank? I have a newer tank but when I replaced it a couple of years ago I found that the orig tank was nearly spotless inside. I would never have guessed it to be so clean. I was just concerned that a 50 y/o tank might rust through and leak while we were away and dump 20 gallon of ethyl on the garage floor for the pilot light in the water heater to play with.

In reagards to the routing, I think that would be feasable but but in my mind I thought it would be harder because there isn't room under the little protective cover that's just forward of the back tire and I was concerned about clearance in the front as well. In reastrospect it probably would have been the better way to go because I would not thave ended up pulling both fender liners.
I came up with a plan to use these: https://www.ebay.com/itm/1973-1979-Chev ... 2749.l2649. One "hump" would carry the fuel line while the other will carry the electrical. I think this will look very clean or almost OEM from underneath.
I'd probably route it as you describe if I could do it over though.

I'll post some pics of the pump and lines when I get all the rest of the parts to finish.

While I'm waiting on plumbing parts, I'll continue on with the other steps.
Today I modified the linkage. There is no kit to adapt our stock throttle rod to a Holley linkage so I purchased one of the kits from jegs: https://www.jegs.com/i/JEGS/555/15730/1 ... UvEALw_wcB

I cut the end of the rod off and used a 10-32 die to thread the end (not shown)
Image

You simply attach the ball to the EFI's linkage and screw the quick release onto the end of your throttle rod. Makes a nice professional connection that wont come apart accidentally. (new thorttle rods are readily available if you ever want to go back to your stock carb). You could even just use a piece of 10/32 All-thread.
Image
I also bent a jog into the rod to better allign the linkage.

You'll have to shorten your air cleaner stud as well.

Next: wiring! (Yay?)

No, I have rust in the trunk, brought on by a perforation somewhere under the rear vent. So, for EFI, I know I need to drop the tank, pull the rear window and vent, fix the rust there, then fix the rust in the truck. Ug. Will be nice, though, to have a dry trunk after washing the car!

Threading that rod is a good solution--safe and secure.

I know you don't run a stock manifold with the water jacket spacer. Where do you route the heater hose?

Steve, since the water just flowed straight through the spacer, I installed a single hose that runs by it.

Since I'm still waiting for parts, I started on the wiring - the ugliest part of this thing.

It needs a good 12V gin source before the resistor wire. Do you know where you have to get that? From right behind the ign switch!
There's no nice way to do it either so I used the least invasive or hack type of tap into the Red/Grn wire, I peeled back some insulation and soldered it. Really hated doing that but it's all I could come up with. I wrapped it in Electrical tape after the pic.
Image
Getting good flow on a 50 y/o wire isn't easy.

I also routed the new ign wire and the EFI's display wire thorugh the Firewall. The display will reside in my glove box.

The big challenge I have now is making this UGLY abomination look OK in the eng. compartment. It has to be place near the back of the throttle body, probably on the fire wall.
(Spooled blue wire goes back to fuel pump)
Image
Pic doesn't do it justice. There's also a bunch of big clunky connectors for this harness, an option for Elect. ign and all the sensors to deal with.
