Hazard

The impeller (resin fan wheel) in the low-pressure fuel pump may swell and deform due to improper molding conditions resulting in low resin density, which is susceptible to swelling from fuel. As a result, the impeller may contact the pump housing, causing fuel pump malfunction. In the worst case, engine stall during driving may occur.

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 unit on all vehicles.
