Is it leaking from the threads, swivel, or around the macroline? If it's leaking around the macroline then you might need to change the oring inside the fitting. To change the oring you need to remove the macroline and retainer clip from the fitting and reach inside with a pick to remove it...the oring is a 010.
Tighten the macroline fittings, add a small drop of oil to the macroline fitting o-rings (on inside), make sure macroline is cut to the right length so it doesn't have to bend or stress when hooked-up, and that ends of the macroline are flat. Might have to just replace the macroline fittings - the DP ones suck
