1991 BMW 535

Report Date:
April 11, 1994
Campaign Number:
94V066000
Component:
FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Summary:
FEED FUEL HOSES CAN HARDEN AND "SET" OVER TIME, ALLOWING A SEEPAGE OF FUEL AT THE CONNECTION BETWEEN THE HOSE AND THE ENGINE FITTING. THE CLAMP USED TO HOLD THE HOSE TO THE FITTING IS UNABLE TO COMPENSATE FOR THE HARDENING OF THE FEED FUEL HOSE.

Consequence Summary:
FUEL SEEPAGE BETWEEN THE FEED FUEL HOSE AND THE ENGINE FITTING CAN RESULT IN FREE FUEL IN THE ENGINE COMPARTMENT, WHICH COULD RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.

Corrective Summary:
A REDESIGNED FEED FUEL HOSE AND HOSE CLAMP WILL BE INSTALLED TO ALLEVIATE THE FUEL SEEPAGE.
