In about 1973 I had the fuel line on my VW van disconnect from the top of the inline standard fuel filter located in the stock position and the result was a cooked engine bay and all the accompanying lines, wiring etc.
Not fun. This was a well maintained and excellent running bus, until then. Took some work and money to get it back into shape. If the body had been fiberglass I don't think the car would have survived at all.
I am a fan of moving fuel lines, filters and pumps as far from potential ignition sources as possible.
