Loss of road speed, hesitation, or engine stall on the subject vehicles operated at ambient temperatures over 85~F or at elevations over 4,500 feet, may
be the result of fuel vaporization. A modification kit is available for vehicles experiencing this condition. It consists of an in-tank fuel pump, inertia
shut-off switch, motorized fuel selector valve, vapor separator, and a vapor return system, along with related fuel lines and electrical wiring and devices.
Before this modification is considered, other factors that could result in the same symptoms should be evaluated. Some of these include:
^
Plugged fuel filter at carburetor or tank.
^
Restricted fuel line.
^
Contaminated or low quality fuel.
^
Malfunctioning fuel pump or carburetor.
If it is determined that the above factors have not caused the customer concern then the appropriate modification kit should be used to change the fuel
system.
