Well, I might as well get this thread started since I intend to move forward at a fairly quick pace. I traded off my spare wagoneer for a full MSD Atomic setup with an in tank pump.
For the time being, the ignition will remain duraspark. Once the system is in and running, I'll likely go with an MSD dist and 6A control box so that the whole setup will communicate and control timing.
So. The first order of business is getting this in-tank pump figgered. I didnt want to trash my 1973 tank so I picked up a 1978 tank and filler neck. sucks that I'll be going to the narrow fill tube, but it is what it is. Also this will let me use the stock sending unit too. The 78 tank I picked up is clean as a whistle inside, so I'll just have to cap off the vent lines and the rollover line (fuel pump mounting flange provides for a vent line with a little included rollover valve).
I need to cut a 4.5" hole for the pump setup, but I need a total of 6" (more or less) clearance for the mounting flange. The location for the stock pickup is about 6" wide, but only about 4.5" deep so I am going to need to massage the metal a bit. I attempted to remove the lock ring retainer from the tank so i could relocate my 4.5" hole a little further towards the front of the tank (but still clear the interior baffle)
This was the ideal location but the lock ring retainer is under the flange and it will not work. I had to shift the flange forward.
as you can see, I'm going to have to massage a few parts of the tank to get that extra clearance all around. I'm going to cut the hole tonight and begin banging on the metal (the tank will be filled with water, yeah yeah "thats not safe" I know... i'm aware of the dangers of tanks and fumes and sparks, etc).
So, if I screw this up (which I will) i'll maybe go with a bronco tank.
Once the tank is prepped, I'll be able to drop my tank, and I already have -6AN braided hose running from my tank, to a filter, to an electric pump, then up to the carb through another filter in the engine bay. I will likely be able to place the new AN fitting 40 micron filter in the same location as the one I have now (back near the tank). I can then install the regulator/gauge/return line unit right up on the firewall where I currently have a filter installed in the braided fuel line about a foot away from the carb/future EFI unit. So, the cool/good news is that the supply line is already mostly run/plumbed.
Hopefully I can get this tank modded correctly and it'll bolt right up where my current tank is, then connect to everything just fine.
I'll need to figure out where to run the vent line from the tank. Perhaps i can just tie it into my original little check valve that's located in the rear fender via hard nylon lines, and keep my stock charcoal canister? But I was hoping to delete that thing from under the hood.
Anyway....stay tuned.
Well it ain't just the smoke and the traffic jam that makes me the bitter fool I am But this four-wheel buggy is A-dollaring me to death.
