Hello!
My '83 300D Turbo does not have a few components in the fuel pump and the IP that you all seem to have on your cars. I'm missing the light spring and bearing inside the Relief Valve bolt that attaches to the engine-side of the IP that meters the fuel exit from the IP and I don't see a plastic metering piece w/ washer beneath and inside the intake line connection on my fuel pump that meters the fuel flow just before the 'lift' inside the fuel pump. I know that there is a valve on the bottom of my fuel pump facing up that may have the 'T' shaped piece behind it I'm speaking of. I'm the 2nd owner of this fine vehicle and it was quite 'virgin' when I bought it and I've been very respectful of the OEM aspect.
Thanks for sharing the wealth of information you all have on this great site!
