Dang - I got the 100 filler PN from Japan 4x4 but its on my now TU HDD whose files I haven't been able to recover yet. Still hoping to get some practical experience from your fitment for my mods for the Tacoma fall project. Concerned about the 100 filler size and space I have for the drop to the tank... the fuel filler door on the Tacoma is just above the wheel well and possible vertical drop into the wheel well, so may have to fab a Y-type filler anyway.
Got an XJ tank (20 gal) with skid plate that fits perfectly between the frame rails where the spare tire used to sit. Fuel inlet is on the same side as the OEM filler and the tank inlet is recessed making for a tucked in fit for the plumbing.
