If this loop goes up a bit to where the top of the loop is higher than the level The last time I saw this was on a Taylorcraft that had been converted to a C-85. It had a big loop of line between the fuel tank and gascolator. Periodically, if the engine was hot, it would start and run just long enough to run all the fuel out of the carb and half of the fuel line, then would simply die and refuse to start again until it cooled down a bit. Sometimes that was during take off roll.
