I always order mine from Phil. I sometimes get Mann, other times Knecht. They always have extra orings my application doesnt use (simple bolt).

I think "kill switch" is a better term for the button mounted on top of the fuel filter.

The shutoff valve is the black plastic electro-hydralic valve on the side of the IP. That oring BTW is 2.5mm x 12mm OD.
