We are very saddened to report that the lovely 1974 DS23 5-speed (carbureted version) of Daniel Noiseaux caught fire on the way home from the Saratoga Springs Rendezvous on Sunday June 17. It happened in Montreal after a long drive in 30 degrees celsius temperatures. A fuel line burst apparently… (Same old story. People really need to check and replace fuel lines that are 10 years or older).
We don’t know if the car is salvageable or not, the fire brigade put it out but it looks heavily damaged in the engine bay and interior.
The burn was recorded on video. Here’s a link to the movie if you can bear to watch it:
What a shame!
Be sure to check the fuel inlet nozzle on your carburetor for looseness or leakage. The fuel hose (8mm or 5/16”), runs upwards from the fuel pump to the carburettor and is clamped to a tubular brass fitting, where it joins the inlet strainer housing of the carburettor. This fitting is an 8mm diameter tube with a plain smooth outside surface. In manufacture, the fitting was pressed tightly into the soft die cast alloy housing. With time, heat and vibration the soft alloy housing becomes “relaxed” and the tube becomes loose in the hole. This can leak fuel, but worse still, it can drop out. If this happens while driving, fuel continues to be pumped out onto the hot engine, resulting in a sudden and destructive fire.
One solution is to ensure the brass fitting is secure in the carburetor gas inlet then use a 3″ long scrap of Ligarex band that you wrap around the carburtetor and a hose clamp that you attached to the fuel line going into the carburetor. Like in this photo:
