I’m 3 for three fails and cannot figure out how to get the bag to hold vacuum. At each connector port I’m even sealing where the hose goes through the bag with a five minute epoxy adhesive around the house before I apply the yellow sealant tape. Using a T fitting through the bag at the vacuum end.  Stretchalon 800 bagging material. Here is a photo. Two full days, an entire weekend into this and I cannot get it to hold vacuum. Thanks for your help and suggestions. Allen
