Uh, does any one know what this is? 3000GT 1 1/16" BMC PN# 54311 in the pic below. It looks like a cup and it slides down inside and loosely sits in the brake fluid reservoir. It sits above the fluid level sensor.

I was looking at the new BMCs yesterday, trying to decide whether to swap fluid reservoirs with the Montero Sport reservoir and noticed the 1 1/16" BMC had this 'cup' thing inside. It immediately made me think of fuel cell baffling for anti-slosh or starvation. Neither of which make sense to me on a car. I know the GT will pull 1G+, but .... This would make a lot more sense on an off road vehicle if its what it looks like.
