Hazard

The impeller (resin fan blade) in the low-pressure fuel pump may swell and deform due to improper molding conditions resulting in low resin density, causing swelling when exposed to fuel. This can cause the impeller to contact the pump case, leading to fuel pump malfunction. In the worst case, engine stall may occur while driving.

低圧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 part on all vehicles.
