Abstract: A diesel fuel system includes a reservoir containing diesel fuel. A suction tube extends into the reservoir and has an inlet so that fuel can be suctioned into the suction tube. A fence is erected around the inlet to prevent ice wafers from entering the inlet and blocking the suction tube. The fence can be mounted on the floor of the reservoir. Or, the fence can be mounted on the suction tube.

Abstract: A motor vehicle filler pipe flame arrester and fuel flow straightener configured to effectively quench a moving flame front, while providing laminar fuel flow therethrough. A multi-channel (or multi-cell) configuration, most preferably a honeycomb configuration, provides effective flame arresting due to its heat sink capacity and large effective surface area for flame arrestment, while attendantly limiting availability of fuel and oxygen to the flame, thereby providing quenching of a flame wave as it propagates through the channels. Service station pump nozzle shut-off sensor disruption is avoided because the channels encourage laminar flow of the fuel through the multi-channel filler pipe flame arrester and fuel flow straightener.
