+x Kacordy - 9/4/2020 5:51:22 PMI just bought this complete vacuum bagging system. It’s brand new. I cannot get the gauge on the pot that catches the excess resin to show the negative vacuum pressure? The pump works and pulls and holds vacuum in the pot. I can release the clamp I have on the hose that goes to the bag and it relieves the pot of vacuum when released. What am I doing wrong? Thanks, Allen
