Common Causes of Failure

Rust is the primary cause of failure for filler necks.

Over time, ambient air and contaminants will cause corrosion on the outside of the filler neck. If left unchecked, corrosion will eventually create holes and cracks in the main pipe body causing it to leak fuel to the ground and vapors into the atmosphere. Cracks and/or holes in the vent hoses can also cause fuel to leak onto the outside of the filler neck, accelerating corrosion around the fuel tank area. Rust in the tank can contaminate the fuel and cause further damage to the vehicle.

Failure to replace or repair the damage may cause vehicle to lose power
