Thanks for the great info and speedy replies, guys! I thought I should mention that the ugly yellow tubing coming off the left side of the box (right as you look at in the picture) seems to be a vent tube as well, it goes down and out the bottom of the belly pan. Does that seem correct? Do you figure the fitting with no line on it is for venting as well? I did notice injection oil dripping out of the fitting with no tube, so I think directing that oil out the bottom makes sense.
