A friend of mine from years back had a 1965 or 66 Ford 1/2 ton. He moved from Saskatchewan to Kelowna, BC. He made a couple of trips back and forth to get everything moved, etc.. Every time he got just past Calgary heading west on the Trans-Canada, the truck would start acting up and eventually conk out. He would let it sit for a while, fire it up and head out. He had the garages check everything they could think of, still did it. His nephew used the truck back in SK for harvest, and I went with him to take it back to BC. Sure enough, it conked out past Calgary, just as we were getting into the mountains. We let it sit for a while, and away we went.
Well, Uncle Willie had had enough and was tired of taking it to garages to try to find out what was wrong. Finally, he took the fuel tank out and emptied it out. He could hear something rattling around in the tank. In the end, he found a flat piece of hard plastic about the size of a silver dollar in the tank. The plastic never caused a moment's trouble when driving around Kelowna, nor out on the Prairies. As soon as the truck got to the hard curves on the highway past Calgary, the stupid little piece would slide over the gas outlet in the tank and shut off the fuel supply. When the engine was shut off, the piece would slide away to rest until the next round.
