Thanks to all the people who responded. I found the balance pipe, it was still in the car but I didn’t recognize it until it was described. I now have all the parts. Is there a way to test the fuel gauge sender before getting all this stuff bolted in ? I have a multi-meter but have no idea what the ohm readings should be between empty and full . Also is the rubber connector on the fuel inlet side available ? Mine "looks" ok but probably should replace it while it’s all apart. Bob
