Finally figured out how it was supposed to fit....
Image
The front mount will fit in nicely with my sway bar frame mounts....
Image
Some slight modification required here....
Image
Another view....
Image
This will be easy....
Image
Gotta cut a 3-1/4" hole for the Aeromotive fuel pump and fuel well....
Image
And will cut and fab a removable piece of the trunk floor over the fuel pump....
Image

More Later....

Got some more work done on the fuel tank....
I trimmed the front support angle to get a better fit on the sway bar frame supports....
Image
If I mount the fuel pump in the front of the tank, left side of the trunk floor is the easiest to cut an access hole for future removal and maintenance....
Image
So I went ahead and cut the required 3-1/4" hole in the front left part of the tank....
Image
Cleaned up and smoothed the rough edges of the new hole....
Image
I propped the tank up so that corner was lowest to keep the mess mostly located right under the hole, and it vacuumed out nicely....
Image
Aeromotive supplied a jig to drill the holes for the new fuel pump....
Image
The idea was to drill two holes opposite each other, then keep it located with these two screws while drilling the rest of the holes...
Image
However, my drill bit went 'south' on the second hole, so I'm going to have to resharpen this bit after each hole, or go buy a couple more bits....
Probably will end up doing both....

More Later...
Aloha,
Willy

Cleaned up the drilled holes for the fuel pump, inside and out....
Image
Used the shop vac to suck out all the debris....
Image
Put the inside ring with the screws in place,,,,
had to file some of the holes to get a good fit....
Image
The nuts are removed after the inside ring is pulled into position...
It is a tight enough fit that it stayed in place....

The front of the tank is 9-1/2" deep (28 gallon tank)...
so the foam is cut to 10-1/2"....
The tank tapers to 9" deep in the rear....
Image
And stuffed down in the tank and massaged back into shape and into position

Then the foam gasket is put on top....
Image
The pump assembly is also assembled to match the 9-1/2" depth...
Image
Had to readjust the foam fuel well a couple of times to get it right....
Image
I think it's good to go....
Image
Now to work up some front mounting brackets....
Image

Rolled the chassis out from under the body,
easier to work on the fuel system....

Loosened up the bolts in back, jacked up the front to cut some more
metal off the front brackets on the tank for a better fit....
Image
While it was up, got in there and ground off paint, cleaned up weld areas....
Image
AND fitted a piece of 3/16 to weld on as a bracket on each side..
Image
Both sides welded on, tacked on while
clamped to the fuel tank to keep then located...

Man, this SS was the toughest stuff to drill I've ever run across....
Using Ace's best bits, I went through 8- 1/4" bits, and 4- 3/8" bits
and that was with a drilling lube and running slow speed, and resharpening
bits with a "Drill Doctor"....
Image
Using cad plated 3/8" bolts, 3/4" long, with flat washers, cad plated, both sides,
a lock washer and a regular nut.
Image
Will pull it out to paint the recent welds,
and I want to coat the welds on this SS tank....

Since I painted the frame with Rustoleum
Black Hammer Tone, decided to do the tank
with the same....
Image
It took two coats plus a little bit here and there, but it looks good to go....
