I managed to get the vac pipe the bulk head, all was plumbed in except for the joining up at the dv, cut through the pipe, went to slide the t-piece in and the pipe deteriorated in my hand! Couldn't believe it. This gave me a reason to order some nice new blue vac pipe off of eBay lol. In the mean time if replaced the pipe using a cut off of clear washer pipe as a temporary measure
