Hazard

Some fuel filters have insufficient wall thickness in portions of the flange surface due to molding defects, resulting in inadequate strength. Consequently, when fuel filter internal pressure rises accompanying pressure increases in the fuel tank due to external temperature fluctuations and other factors, cracks may form in the flange surface, potentially causing fuel odor or fuel leakage.

燃料フィルタにおいて、成形不良によりフランジ面の一部の肉厚が薄く、強度が不足しているものがある。そのため、外気温度等の影響による燃料タンク内の圧力上昇に伴い、燃料フィルタ内の圧力が上昇した場合、当該フランジ面に亀裂が入り、燃料臭や燃料漏れが発生するおそれがある。

Remedy

Replace the fuel filter with a serviceable unit on all vehicles.
