I've not seen a ready source as well.
Not sure what the difference is between the pins, but for the 1HD-T JDMs
22321-17140 for 01-90/03-91
22321-17281 for 04-91/07-92
22321-17420 for 08-92/12-94
1HD-FT
22321-17840 for 01-95/12-97
@yotahed maybe has some ideas? I know he was/is doing fuel pin mods so the pin has more stroke:
The Official 1HD-T/FT Fuel Pump Mod Tuning Thread
Thought I head someone in NA was going to to do a run of pins but I have not heard anything else.
Looks like 4Wheelauto still has the Zeal fuel pin, but that is modified.
Have you tried @Japan4X4?
