Summary

VEHICLES MAY EXPERIENCE PERFORATION OF THE FUEL PUMP DIAPHRAGM. EXCESSIVE ALCOHOL CONTENT IN THE FUEL PROMOTES DEGRADATION OF THE DIAPHRAGM COATING RESULTING IN RADIAL CRACKING OF THE DIAPHRAGM.

Consequence

A PERFORATED DIAPHRAGM CAN ALLOW FUEL TO LEAK FROM THEFUEL PUMP INTO THE UNDERHOOD AREA. THIS COULD ULTIMATELY RESULT IN ANUNDERHOOD FIRE WITHOUT PRIOR WARNING. SUCH A FIRE COULD SPREAD TO THEPASSENGER COMPARTMENT.

Remedy

A FUEL VENTILATION HOSE KIT WILL BE INSTALLED TO PREVENT FUEL FROM ESCAPING INTO THE ENGINE COMPARTMENT IF THE FUEL PUMP DIAPHRAGM LEAKS AND THEREBY REDUCE THE POSSIBILITY OF AN UNDERHOOD FIRE.
