Just thought I'd mention a business called Lift Parts Warehouse. They're a US based supplier of fork lift part, including Toyota diesel lifts apparently. I was able to order several parts for the fuel filter assembly on my 1991 HDJ81. The parts pricing is lower than most other suppliers, plus much lower shipping than the over seas toyota parts suppliers. Not sure how extensive their inventory is, but you might try them.
