i am having an 8.8 rebuilt and 3.73's installed into it. i noticed that the 8.8 has a vent plug, whereas my 7.5 does not. do i need to attach tubing to that nipple, or will it be all set as is? the reason i ask is because i have seen some pickups come into the shop with actual tubing attached to the plug and then connected to the rear axle.
