Hazard

The fuel pump impeller (resin rotor) may have reduced resin density due to improper molding conditions, causing it to swell and deform when exposed to fuel. This can cause the impeller to contact the pump housing, resulting in fuel pump malfunction. In severe cases, engine stalling while driving may occur.

燃料ポンプのインペラ(樹脂製羽根車)において、成形条件が不適切なため、樹脂密度が低くなって、燃料により膨潤して変形することがある。そのため、インペラがポンプケースと接触して燃料ポンプが作動不良となり、最悪の場合、走行中エンストに至るおそれがある。

Remedy

Replace the low-pressure fuel pump with a corrected unit on all vehicles.
