ok heres the scoop i have 98 civic dx hatch with a b16 in it. the swap was attempted by 3 people in the area and noone could do it so i finally took it upon myself to learn how to do to like 2 year ago, but just last week i was looking my motor over and found a hose tucked away. the hose was clear with kinda a smoked hue to it that runs from under the car and stops right near my evap canister. it has this weird fitting on it that is black and has a square plug on the end with a round piece that when i is hooked up to whatever it goes to all you see is that round part as the square fits inside. WHAT IS THIS HOSE AND WHERE DOES IT GO? i thought it may hook up to the evap system but i cant find anywhere where it should hook up

 

it hooks on to the fuel filter bracket.

 

where on the filter, and what does it do got any pics

 

 

ok, all is well now, thanks, but im still wondering what exactally that hose does
