Fattest part of the pipe, on top between 9 o'clock and 3 o'clock. That's what I've always been told, and mine works great there.

11 o clock on the inside bend of the pipe (fattest part), fuel/oil will favour the outside bend of the pipe and that's what kills the sensors.

If the sensor is to horizontal fuel/oil & moisture can trickle in and shorten the life.
