When you say leaking through the "front air attachment" do you mean the fitting itself?
The straight fittings on the POPS do not need to be Loctited in, they simply require tightening using the correct size allen key that fits in the middle of the fitting (when no hose is in place). If teh leak was coming from the hose, then check that the o-ring inside the fitting is not damaged (or missing) and replace the hose if necessary.
