Mention that this example is a worst-case: leak begins as far from sensor as possible (at upper right side of pipe).
Point out leak start, sensor and well-screen pipe

Note 20 hour time required for first few milliliters of fuel to contact the sensor. THIS IS WHY SENSOR MUST BE HIGH SENSITIVITY. If it were not high sensitivity, it could take many days for sufficient fuel to soak the sensor enough to cause an alarm. 21 20 10 5 3 1
