I am infusing ly556  resin and hy951 hardener with glass fibres to produce laminates of size 300mmx 150mm with 2 mm thickness. problem is as soon i open the resin line for infusion, resin accumulates around the line ad leaks out between bagging tape and vacuum bag. please help to resolve this problem

This is very strange, as the pressure inside the bag during infusion should be lower than the atmospheric pressure. So the resin should not have any reason to flow out. Instead air should leak in. So I guess there are some problems with your setup
