Could you be a little more specific? Try to think your questions thru a little better...

I have done this swap
Intank pump hanger is a total you design and fabricate. no one commercially makes a hanger. I used a ebay 255 Walbro pump and went from there. I used a new tank and cut a hole for the my fabricated pump hanger.
The Walbro is noisy. NO REALLY NOISY. I am going to switch to the Deusctewerke (SP)pump real soon.
But nothing oof the shelf right now for what you want to do.
Exhaust is the same for SBC.

Do yourself a huge favor and put that tank between the frame rails in the rear.

It would be much easier to run an external pump. I've used Bosch 044 external pumps on a few swaps with great success. Use a C5 FPR. Plump the return line back into the tank.

You can hear the Bosch pump run at idle but as soon as you go down the road you can't hear it over the engine or road noise.

Just .02 worth.
