1. A fuel line coupling component for coupling coaxially aligned first and second fuel lines to allow displacements therebetween, wherein the fuel line coupling component comprises:
an outer tubular member having a coaxially aligned pair of outer tubular sections that are coaxially displaceable relative to one another;
an inner tubular member which is coaxially sleeved within the outer tubular member so as to define an annular space therebetween, the inner tubular member having a coaxially sleeved pair of inner tubular sections that are coaxially displaceable relative to one another; and
a pair of flanged terminal end connectors to allow connection between and to opposed ends of a fuel line, wherein the terminal end connectors comprise
(i) a journalled connection assembly with the respective opposed distal ends of the outer and inner tubular members to thereby allow simultaneous rotational movements of the outer and inner tubular members about a longitudinal axis thereof and simultaneous radial displacements of the outer and inner tubular members relative to a reference plane, and
(ii) a series of radially extending connection lobes which are circumferentially spaced apart from one another.
