Recall 12V524 affects 6,520 2012-2013 Mitsubishi Fuso FEC-series and FGB72 trucks for fuel-filter-head connector defects. Repair is free at franchised Mitsubishi Fuso dealers.
Mitsubishi Fuso is recalling 6,520 2012-2013 FEC72, FEC52, FEC92, and FGB72 trucks because an improperly machined connector lets the fuel line disconnect from the fuel filter head.

What's wrong?
The fuel filter on 2012-2013 Mitsubishi Fuso FEC72, FEC52, FEC92, and FGB72 trucks cleans diesel fuel before it reaches the engine. The fuel filter head is the housing where the fuel line connects to that filter. That connection has to stay tight so fuel keeps moving through the system without losing pressure.
On affected trucks, the connector at the fuel filter head was improperly machined. Because the connector shape is wrong, the fuel line does not lock onto the filter head as designed. During normal use, that loose fit can let the line separate from the filter head. Fuel flow stops at that point, and fuel can escape at the connection.
There is no warning sign before failure. The first sign an owner notices can be fuel around the filter area, fuel smell, or an engine that stops running after the line comes loose.
