The below image shows a special fuel tank AC Cars made for my Superblower. You may be able to see thast it suts in a cradle in the boot (trunk)
The next image shows the tank now owder coated black. Excuse the dust!! You may be able to see two fuel bosses. One is the fuel feed, the other is the fuel return.
The bosses are 3/8 NPT threads.
The EFI fuel pump is mounted on the port side of the differential, the pre-pump filter on the starboard side of the diff.
Hope this is of some help.
