Tilton-it was a pretty good spray that I saw in the same spot you mentioned.

Pranav-sorry I really don't grasp all the catch tank venting stuff you have going on. Don't really know why you are having trouble other than it seems like it all may have been messed with. Don't really see any issues when using the stock tank. Now what I did think I understood is you have a catch tank for GAS mounted somewhere with the breather hose going to the back bumper. I've burned enough hair off my body to know that some gas fumes with a hint of spark are going to blow up-so to me it is concerning that you have a hose full of gas fumes on your back bumper where you might get hit causing a spark or underhood fire from the car behind you. Also, guess its good that Burch isn't smoking cigs while racing anymore.

That being said I have zero idea how the stock tank works for venting or anything but I have a stock plastic tank in the backyard I'll check out this week.
