The Turbo LDA (on top) should not add much work, but it will change the seal kit you'll need (I think). Here's a nice write-up about changing the seal on the LDA slide-pin:

Other than that, some quick tips:
1)You can make the special tools you'll need for the pressure regulator and the triangular bolts with a Dremel and a burin or cutting tool and some old sockets.
2) To hold parts in place during assembly that might otherwise fall out, I like Vaseline.
3) I like to really clean the hell out of the outside and insides of the case. To do so, I get a variety of small wire brushes and wheels for a Dremel, and use them in my angle grinder collet.
4) Be sure to SCRIBE anything that fits overs a splined shaft for reference.
5) For the governor shaft (the one with a lock-nut and allen in the center), I like to CUT a mark on the outside of the nut to the center shaft with a small disc cutter (like a dremel one).
6) To get out the feed/vane pump: Early cars used 2 Phillips screws, later pumps used Torx screws. If you have the Phillips screws, buy a BRAND NEW, extension screwdriver with a good tip. Hold the pump in your vice (carefully, but sturdy) so you can look down into the pump. Set the screwdriver into the screw, and give it a few heavy whacks with a heavy hammer. This will help free up the threads, and allow you to remove the screws without risk of stripping the heads. Otherwise, you'll have to drill out the screw heads, and good luck finding replacements, unless you pull them from another pump.
This is the root cause of your problems (inability to pull fuel from the tank, and lack of internal pump pressure). I'm sure you'll find 2 or more of the vanes (little tabs in the feed pump) will be stuck in place. They should move in an out freely. If you need to, remove the tabs and lightly sand (with no lower than 2000 grit) the sides so that they fit snug, but slide out easily. Or, just work the tabs in and out with some penetrating oil lubing it up.Put some Vaseline on them during the install back into the pump housing to prevent them from falling out. The Vaseline will wash away in short order.
Good luck!
Oh, lastly, be sure to REFERENCE the keyway on the input shaft with the cam-plate and plunger, or else your timing will be 180 degrees out. It's well-covered in the online "how-to", but I still managed to screw it up on the first 2 pumps I did.
