Just got me a '05 Screw 5.4 4x4. Went to fill it up and noticed that there was no little anti-siphon flap (the little aluminum piece that you push in with the gas nozzle. Thought it was broken off.
Called the dealer where I bought it and they ordered another Gas refill tube assy. Opened the box and viola it appears it is made this way(without the flap). Can a few of you guys check and see if you do or do not have the little flap under your gas cap. My '97 has one. I thought it was required. Where I live here in TN we have emissions testing so just wanted to make sure.

Sorry for the long post and Thanks in advance for the replies! Merry Christmas!!!:santa:

 

I don't have it in my 03.
The anti siphon device is further down and you cant see it but it's there.
Try sticking a hose in there and you'll see.
