Since the VDO send unit is working perfectly, I am going to leave it for now. But I do need the O-ring. I am going to replace the fuel pump and some of the fuel line. W&N has identical cloth woven fuel line. I will try to find it and the O-ring domestically. Also, I am looking for a (1) round chrome plastic piece/insert that goes in the wing window control and a cap for my window washer fluid. Any ideas? W&N has everything, but the shipping is more than the parts I need, so I am looking in the States.
