You'll need a vn commodore tank with the efi pump, take it and the carby sprinter tank to a metal fabrication shop and ask/get them the remove guts of one and place into the other, simple really, and it only cost me around the $275 mark.
No possibility of smells, no unnecessary efi lines, safer cleaner.
You will need to upgrade all rubber fuel hoses to efi grade hose. The standard stuff wont last long.
