OK, so I FINALLY got this done. BUT I decided to do it the "right" way...the closest to OEM spec way that I could get for what resources I had available.
First of all, buy yourself a set of turbo sockets....IRWIN makes a set, and they're not all that expensive...I think $24 bucks total. These will help you TREMENDOUSLY, not ony with this project, but for any other stuck nuts/bolts you may have on your GVR4
I will say to cut things short, the only additional information I'd add to the VFAQ would be that instead of a 19mm flare nut wrench, use a 3/4 wrench, AND USE THE TURBO SOCKET TO TAKE OFF THE RETAINING NUTS, if you dont, you will have rounded, rusted nuts that will be the pain in your side, and deprive you from sleeping for a good long while.
On to pics and explanations
Using the turbo socket takes 5 minutes...without it you could spend hours

Side by Side comparison 1G on the left, as you can see the fuel fill sensors are only secured by TWO tiny phillips head screws, remove them and at a later step, you will re-install the GVR4 unit

Comparison of the fuel sensors...the 1G is longer, so remove/repalce

Dissasembly of the FSU's is straightforward, use your common sense here, everything on these units are either phillips screwdriver or 7mm bolt/nut.

Naked bracket comparison

Carefully drill out the spot welds from each bracket and use a vice to hold in place, use a metal shim, and hammer it lightly in between the top of the sending unit and the bracket to remove the bracket, this is a delicate process and takes the most time, so please be careful while doing this

What the bracket looks like off the unit

Now here is the ringer, if you have access to a welder then you're ahead of the curve, before re-assembly, you want to weld the bracket back in place, if you dont have access to a welder, I assume you could use some sort of JB Weld polymer to adhere bracket to top.



NOTE: you will have to cut the lower pipe from the 1G fuel sending unit and connect it with a rubber hose (I used 5/8" fuel hose) in order for the fuel pump to fit.
