Steering pump rebuild

[whitefinish]

I've been rebuilding my steering pump due to untraceable leaking of the damn thing.

This is the rebuild "guide" that I've followed.

The rebuild is not much of a problem, but I can't find the correct plastic seal ?

It says something like this

@4c9f37023a:

NGK 57 ae10171 or ae1017i or ae101z1 or ae101ZL

Who know what it says and where to get it ?
