Common 1W-1695 Fuel Pump Problems

A worn or damaged fuel transfer pump may be unable to maintain the fuel flow required by the engine injection system. This can cause difficult starting, irregular engine operation or reduced power under load.

Common signs of fuel transfer pump failure include:

Hard or delayed engine starting

Low or unstable fuel pressure

Irregular engine idling

Engine hesitation during acceleration

Reduced power under heavy load

Intermittent engine shutdown

Fuel leakage around the pump body

Abnormal mechanical noise from the pump area

Replacing the failed pump with the correct 1W-1695 replacement can help restore stable fuel delivery and normal engine operation.
