There are two sealing washers.

The lower one is convex one side and concave the other. - The CONCAVE side goes uppermost.

Here are my new washers in place ready for the injector to be screwed in on top:

:cheers:

PS. This picture of the old washers may show their shapes better:

And here's confirmation from the FSM:

PPS. And to satisfy my interest - Do you know any of the numbers for your 3B injectors? (For instance "1800 body" or "DN4 SD-24 nozzles")

You didnt say what 3B you have or what year/model, Im assuming they are all the same but thats for you to check. Im also surprised an experienced diesel fuel injection shop can not work this out.

and i was little surprised that they were asking me as well.

by the sounds of it, they were a little surprised i did not send them an old gasket and seal for reference.

Thanks for fwding the parts spread sheet from Toyodiy.com

Most fuel injection shops have a little library full of old parts manuals. Or they can get inside parts lists online that consumers often have trouble accessing.
The B engines have been used in refrigeration and boats, they are possibly one of the most common 3 litre diesels in the world.
