ABSTRACT:
A double walled hose assembly includes an elongate inner hose and an elongate outer hose enclosing the inner hose. Both the inner and outer hoses are flexible and made of a resilient material. The inner hose includes a fluid resistant inner layer, a tie layer encircling the inner layer and a reinforcing braid layer encircling the tie layer. An outer layer encircles the tie layer and the reinforcing braid such that the reinforcing braid is embedded between the tie layer and the outer layer. The outer hose is also made from a resilient material such that the outer hose is flexible. At least one rib extends between the inner hose and the outer hose. The at least one rib is secured to at least one of the inner hose and the outer hose and is made from a resilient material such that the rib is flexible. In this way, the hose assembly can be bent as necessary. The hose serves as a fluid transfer hose in a piping system for conveying a fluid from an outlet port of a pump to an inlet port of an above-ground fluid dispenser. A sensor wire may be provided between the two hoses to sense the presence of a fluid such as a fuel.
