Defect
On the impeller (resin impeller wheel) of the fuel pump, improper molding conditions reduce the resin density, allowing the impeller to swell and deform when exposed to fuel. The deformed impeller contacts the pump case, causing the fuel pump to malfunction. In the worst case, the engine may stall while driving.
Corrective action
Replace the fuel pump with a corrected part on all vehicles.

状況
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。
改善措置
全車両、燃料ポンプを対策品と交換する。
