To prevent XJ-S coupe engine hesitation caused by fuel vaporization during high ambient temperature/low fuel level conditions, a sump tank venting kit (JLM 2163) is available through Zone Parts Departments.
With the kit installed, there is a vent directly from the vaporator separator feed hose into the sump tank to prevent fuel vapor from being drawn into the main fuel system.
