The OEM fuel filters are, and indeed have been for quite some time, hard to come by. I was having a look around and found these: -
FS481J FUEL FILTER AC Delco ACF115 AC Delco GF111 AC Delco GF481 AC Delco GF621 AC Delco GF626 AC Delco GF651 AC Delco GF652 - Truck Parts and All Filters Hino Isuzu Fuso Mitsubishi Mazda Nissan Ud Toyota Dyna Delta (brettsfilters.com.au)

They come with captive nuts but with metric threads, which I am certain the OEM filters were not. Although the OEM filters for our V8 engines were manufactured within the U.K, they were an American design, the implication being that the threads would likely be National Pipe Straight (NPS).
