ABSTRACT:
A high pressure fuel hose for disposition between a fluid connector on a fuel pump canister in a fuel reservoir and a fluid connector through the reservoir wall. The fuel hose, located intermediate the fuel delivery system and a check valve at the fuel pump, has a flexible tubular body characterized by a plurality of annular sinusoidal convolutions well suited for accepting volumetric and pressure increases in the fuel trapped between the check valve and the fuel delivery system caused by temperature loading of the fuel following engine shut-down. A region of reduced wall thickness is formed in the tubular body to act as a pressure fuse having a predetermined burst pressure allowing system leakage due to overpressurization to be location controlled.
