A basic operation of the very simple optical sensing system of fuel leakagein uniform sandy and clayey soils, which is consisting of a plastic optical fibre (POF)transmission line, the POF-type sensor heads, and a single LED photodiode pair, hasbeen studied theoretically and experimentally. Its sensing principle is based on thePOF structure change in the sensor head caused by fuels such as petrol. A scale-downedmodel prepared in the experimental room showed a possibility of optical detection offuel leakage points in uniform soil. As this system operates without receiving theinfluence of water containing in fuels and soils, its application to fuel leak monitoraround a filling station and oil tank can be expected
