Filing in context
The Fuel Pump is the most frequently cited component category in this archive, appearing in 57 of its 4,890 filings. This filing is one of 150 Mitsubishi notifications from 2004 in this archive. For scale, 1,690 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 4 months.
Defect
The left/right fuel switching valves inside the saddle-type fuel tank are improperly designed. When fuel level drops to one-quarter or below, vehicle vibration may cause the valves to resonate, resulting in seal failure. Air then enters the fuel system, causing engine rough running. In the worst case, the engine may stall while driving.
Corrective action
On all vehicles, replace the affected valves with corrected parts. Because supply of the corrected parts will take time, all owners will first be notified of the defect and advised on precautionary operating measures; the physical repair will be performed at a later date.
