The little brass donuts under the injectors, which way goes "up", the concave or convex side???
Got a pic? Most I have seen are flat. They usually have a chamfered edge on one or both sides around the outside radius.
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:

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")
