I've thought about this a lot overnight Stan. Yes, I did lie awake for an hour or two. Thanks a lot!

The way I see it is this: the baffle is installed from left to right across the tank. Lets assume a low tank level, say only 1/4 full....  on a severe right lean the fuel would run to the RHS of the tank which is where the pickup is located anyway - so no specific benefit. On a severe left lean the fuel might run away from the pickup, but the left/right baffle would not help this, so no benefit either. On a severe upwards angle (hillclimb) the fuel would run to the back of the tank where the pickup is located, so no specific benefit here. On a severe downwards angle, the fuel would run to the front of the tank and away from the pickup. In this case the baffle might slow the rate of drain to the front of the tank because it temporarily confines the fuel to the rear portion of the tank? IDK. There are two smallish drain holes in the bottom of the baffle, one on each corner. You can see one in the pic above. These might slow the rate of drain towards the front of the tank so that you could avoid sucking air when you otherwise might have? Again, IDK. It's an interesting theory. But if the baffle was to be properly effective in this job you would think the engineers would have done the same with a right angled baffle from front to back, to similarly confine fuel to the pickup section of the tank on a severe left lean??? Seems a little silly to engineer half a benefit but ignore the other potential half of the benefit...
