I need a gas cap for my sisters 99 Toyota Camry LE. It keeps loosing vacumm and causes problems with inspection also it doesn't make that clicking sound anymore. I found a place that sells them but don't know vented or unvented? How do i tell

that's not vented. vented has a push button or twist button in the handle middle.

 

Thanks for replying . Yeah it doesn't have any release so ordered the non vented one from JC Whitney with free shipping cost $4.36 . Just wondering if either could have been used and what difference would a vented one make

 

none. I have vented in my pickup. Just something a man likes doing to look inportant - press button in the center of it and listen to hiss sound. They say it's easier to undo, as it releases internal pressure ein gas tank. Hisses it does, that's true.
Don't buy anything from JCW. junk. vented cap is six bucks in a parts store. with onsite return and exchange.
