[QUOTE="ls3denali, post: 84, member: 66"] A few things that come to mind are 1 the oring seal around module not sealing properly 2 maybe the valve on top of tank not reconnected or broke upon reassembly, may be a hose not properly seated. 3 being in the field I see alot of vent valves stuck open and have seen the actual plug on the module where the male pins where not seated ( weather pack) and actually leaked out of the plug.
