I posted that here too – more than once. I was lucky – I got 3 gallons in the tank and two more in the bilge. It is not the fault of Universal Motors though that C&C could not be bothered to use fuel-rated components and I suppose C&C can’t be blamed in 1973 for not foreseeing ethanol gas decades later. Still, that piece they used for a 90 degree turn was obviously part of a sink drain or something and not related to fuel hose even back in 1973.

It was a sistership to my own and I suspect they had the issue I had. A 90 degree rubber elbow C&C used was not fuel rated, but tolerated gasoline. Ethanol, not so much I found the leak in mine and replaced it and discovered my entire fill hose was coming apart from the inside! _____ Joe Della Barba Coquina C&C 35 MK I The following is from a forensic engineering firm - BOAT EXPLOSIONS Boating is an enjoyable pass time for many Canadians. Unfortunately, the dangers associated with this activity are often misunderstood or ignored. Marine craft present a particular hazard to fire and explosions. According to US Coast Guard statistics, fires and explosions account for the largest single cause of marine property damage. The hazards exist owing to the presence of flammable liquids present within confined, poorly ventilated spaces. Gasoline fuel, which is used to propel the majority of private marine craft presents the most common hazard. Gasoline can be released into boat compartments as a result of equipment failure, spills and improper storage of fuel supply. Gasoline has a lower explosive limit (LEL) of 1.4% by volume and an upper explosive limit (UEL) of 7.6%. The percentages within the LEL and UEL represent flammable gasoline/air mixtures. Therefore, a flammable gasoline/air mixture can exist when 100 ml (approx. 200 drops) of gasoline liquid is vaporized in 1 cubic metre (approx. 35 cubic feet) of confined air space. Furthermore, gasoline vapour is heavier than air and tends to collect in lower compartments of the boat. Therefore, a small leak or spill can present a significant hazard of explosion and fire. Diesel fuel presents a reduced explosion hazard owing to its higher flash point which prevents it from readily evaporating to produce a flammable mixture. The LEL for No. 1 grade diesel fuel is 3.5% by volume and the UEL is 6.9%. The LEL is higher and the range is smaller, further reducing the hazard. However, higher temperatures will cause diesel fuel to evaporate more readily resulting in explosive mixtures being present within confined air spaces on marine craft. Temperatures within cabins and engine compartments may be significantly raised by the hot summer sun, increasing this hazard. In addition to engine fuels, galley stoves, which operate with fuels such as alcohol, kerosene, and propane present significant fire and explosion hazards from improper operation, improper installation, fuel leaks and spills. Propane (LEL = 2.5%, UEL = 4.5%) presents the greatest explosion hazard.

Now the fuel might explode, but given the craptastic materials C&C used for fuel systems in the early 70s, odds are the fuel didn’t leak out of the ENGINE ;) BTW – if I were an insurance adjuster, this fire would get a second look…..
