A fluid leak alarm system for detecting leaks in the fluid delivery lines located for example in a fuel filling or bulk station or other pressure lines is designed to have a detector with a pressure sensor mounted into each fuel delivery line of the different product lines and a transmitter for transmitting over conventional electrical power lines a unique code identifying the fuel line in the event of a leak. The fuel leak alarm system is further designed to have a remotely located receiver which is responsive to the uniquely coded signal transmitted over the electrical power line for extracting the signal from the power line and sounding an alarm which identifies the leaking fuel delivery line. A plurality of unique codes identify the delivery lines for the different product lines so that any electrical interference which may be picked up by the power lines is ignored by the receiver which responds only to the unique codes. The pressure detector is further designed to incorporate a bellows driven piston which interacts with a photo switch to minimize the danger of fuel explosion.
