I have done it before, the thick rubber Washer with the 8 smaller holes goes on the "white plastic end" of the fuel pump. The other black rubber washer goes on the "black end" of the fuel pump, the white plastic " C " is just a spacer to compensate for the shorter length of the fuel pump in order to mount it correctly to the sending unit assembly that goes in the tank, I remember I had to trial and error mine a bit and had to actually trim it just a little for clearance, the thin big round rubber washer is for the lock ring for the sending unit and the piece of hose and clamps are pretty obvious, I don't remember if I needed the longer connector and extra plastic clip but a little creativity is required to make it work :thumbsup:
