The vacuum pump is so hard to RxR I feel a need to inform all of a glitch I found in the Cummins Forum pictorial and instructions. The seal directions and picture of the seal coming out are WRONG! They show and explain that the dust seal side of the seal faces the vac pump. The cummins instructions say that the spring side of the seal should face the vac pump. The spring side of the seal always faces the area to be sealed.
