after a little (understatement) spirited driving, there is some fluid that bubbles right at the connection of this black hose, about 1-1.5 inches in diameter. it is located next to the last spark plug all the way in the back of the engine bay. it is connected through the top of the engine, sorry i dont have pics. but if anyone has any idea what this hose is, please let me know. i think it is the fuel line. the other end is connected to some round container, maybe the fuel pump? thanks.
