Abstract: A magnet assembly for holding magnets on and around a fuel line to improve combustion of fuel in an engine supplied by the fuel line, comprises a rubber-like one-piece magnet casing having two integral halves hinged together at one end and spring-biased toward each other. A pair of facing axial semi-cylindrical grooves are formed in the two casing halves, which in use embrace the periphery of the fuel line. A flexible strip-like diaphragm of the same resilient rubber-like material extends across each groove, to provide a spring-tensioned grip on the fuel line when the halves of the casing are urged toward each other. To provide this action, a tie encircles the exterior of the casing and is pulled tight to clamp the two halves of the casing on the fuel line.
