Good To Know

Q: Why should I replace the fuel pump seal when changing the fuel pump? A: Fuel seals compress and swell over time, so reusing an old seal often leads to fuel vapor leaks and check engine lights.

Q: Does this seal require any special lubricant during installation? A: It is best to install the seal dry or with a very light coating of clean fuel to prevent twisting or binding as the locking ring is tightened.

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