'05 Corolla Gas Filler Neck - Corolland: the Toyota Corolla Forums

Does the 2005 Corolla have an anti-siphon screen, trap or device in the gas filler neck to prevent a siphon tube or foreign objects from entering the gas tank? One day, as I was filling up my car, a lady bug quickly crawled down the filler neck before I could put the nozzle in. I'm sure there must be something in the filler neck to keep things out of the gas tank in case an object accidentally fell in (such as dirt, etc. or a lady bug!).

Also, where is the fuel filter located on an '05 Corolla? Is it inside or outside the tank and how often should it be changed?

Thanks.

I believe that they have an anti-siphon trap in there. I wouldn't worry too much about the lady bug - should not cause any problems.

As for the fuel filter - it is inside the tank. In normal operation, does not need changing at all - one of those rough filter deals with a smaller fine filter inside the pump itself.
