Oh, is there an oem filter there?

I just don't have the little black thing in the engine bay anymore, and fuel vapor is quite strong. I was thinking of eliminating that whole line to the engine bay, and just putting a filter wherever it goes on the fuel tank.

I haven't researched this yet. I just figured fuel vapor in the engine bay is asking for a fire.

You should plug the line in the engine bay, then mod the gas cap so it doesn't hold pressure. Otherwise, the only place you can place a filter is on top of the tank, you'd have to find some way to filter it outside the trunk.

Modding the gas cap so it won't retain pressure is kinda like sticking a filter directly on the tank. You can just cap the evap line in the engine bay then, or you can cap it on top of the tank. It will still fume off a bit, but at least it's outside.

I'm not sure how you went about eliminating your overflow tank under the hood that is causing you to have excessive fuel vapor. As for what he was saying about the filter, I believe he was trying to say that the cone filter is far from the filtration a charcoal cartridge provides. That being said, the fuel smell is not a bother to me because the car is very rarely driven so dealing with it on the occasion is hardly a put off for me.

As for the link to the filter, Google search "mini cone filter" And the first Amazon result will get you there.

On my car, I eliminated the entire system altogether with the exception of that hose coming from the top of the tank and ending just above the regulator with the mini cone filter just as you have mentioned. I didn't like the idea of drilling a hole in my cap.

Nice. Step it up to 60-70base, the ids really like that

I appreciate the insight. Guess I'll get back under there and turn it up a little further.

If you take the cap apart you can remove the spring and diaphragm that makes it retain pressure. The rollover valve is in another half of the gas cap, so you can leave that as is without modifying it.

I too would suggest against just drilling a hole in the cap.
