Specs At A Glance

Good To Know

Q: Why is it important to replace this seal whenever the fuel pump is removed? A: Once the fuel pump lock ring is released, the old rubber seal often stretches or degrades and will not reseal properly, leading to fuel leaks or evaporation codes. Always install a new seal to ensure a proper airtight closure.

Q: Should I lubricate this gasket during installation? A: Applying a light coating of clean fuel or a compatible fuel-safe lubricant can help slide the seal and fuel pump into place smoothly without pinching the rubber.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
