Abstract: A hydrocarbon vapour filter system for capturing vapour released from a fuel tank. The system contains a vapour line in vapour-tight communication with the fuel tank, having a vapour capture segment for capturing fuel vapour, and in the preferred embodiment a purging stage releasing the fuel vapour. During engine operation captured fuel vapour can be released from the vapour capture line into air drawn into the engine intake manifold.

Abstract: An apparatus for removing an outer layer from a portion of a multi layer tube is disclosed. The apparatus includes a support assembly which holds the portion of the tube at a preset position. A nozzle is fluidly connected to a source of high pressure water and has its outlet directed towards the portion of the tube. A relative, rotary motion about a concentric axis between the nozzle and the tube directs the water such that it removes the outer layer from the tube portion around the entire circumfery of the tube. In one embodiment, the nozzle is held stationary while the tube portion is rotated relative to the nozzle while in a second embodiment the tube portion is held stationary while the nozzle is rotated relative to the tube portion. The apparatus is particularly useful for removing an outer nylon covering from a metal tube.
