Hello @Mr_FNT .... That short metal pipe that goes inside of the short hose that connects the reservoir and pump is a 12mm Allen. It does have an aluminum crush washer, but since you didn't remove it and disturb the crush washer, you should be OK and it is not likely the pipe will leak at the crush washer anyway. The short rubber hose has two different specs for length, depending on whether you have a ZF or LuK tandem pump (you have the latter pump). As you did, I highly recommend adding 2-3 mm onto the length of the short hose for good measure -- the hose tends to shrink and also get shortened slightly by the two clamps. Also, it is an EXCELLENT idea to re-tighten the two ring clamps a week or two after the system is filled with oil and the tandem pump is used .... this takes into account compression of the new hose. They can seep quickly if you don't re-snug the two ring clamps. For the bolts that hold the pump to the bracket, and the bracket to the engine, indeed there is no torque spec. I use the very old German torque spec that I call "Gutentight" for these bolts. The rubber short hose length spec for the Vickers/LuK pump is 76mm; for the ZF pumps it is 53mm. Add a couple or three mm onto that spec and you should be good.

The seal at 2:04 is for the top of the power steering reservoir. You failed to install it during the reassembly. And definitely heed Gerry's comments regarding the rubber hose. It's a notorious leak spot and it's critical to take your time getting it cut to the correct length and angle at one end and installed carefully or it will leak guaranteed.
The seal I didn't install is too small for the reservoir cap. That's why I did not install it. The seal can physically fit in the reservoir without touching. Also, I mentioned in the video that I will correct the hose length issue.

Is this the same as the w210 e420 from 1997
@@ChrisSickich it is probably very similar.
