Just changed my fuel filter and it went smoothly. Although, when I took out the old fuel filter a foam insulator piece came out and I never put it back in because I thought that it wasn't crucial. After reading through my Bentley Manual it says under the replacement of the fuel filter:

"Note: When installing fuel filter cover, take care to reinstall foam rubber seal in front of cover correctly to prevent flooding of filter with rain splash water."

Does anyone else know anything about this foam piece?
