I ran my breather hose all the way to the back of the car And attached a fuel filter on the end… I installed the grill over the holes, which were originally for the L bumper, and on the left side, the vent tube right behind it on the right side, the coolant overflow.
because fuel vapor is heavier than air and made a trap like you have in a toilet… A low point where it can collect in and it goes up again..
well, I don’t have any smell..👃
