“Fuel pump failure can result in an engine stall while driving, increasing the risk of a crash,” Ford told the National Highway Traffic Safety Administration in the mandatory safety defect recall filing made public by NHTSA earlier this week. “Loss of fuel pressure and flow from the low-pressure fuel pump can be due to internal contamination of the jet pump, specifically in low fuel conditions, and reduced fuel pump internal clearances that result in an increase of internal friction and sensitivity to vapor lock,” Ford said.

Identification of any warning that can occur: Prior to fuel pump failure, the customer may experience poor engine performance (misfiring or running rough), a check engine light, or a reduction in engine power. Fuel pump failure is more likely to occur in low fuel or warm weather and hot fuel conditions in the fuel tank.
