I installed the Rx monster few months back. Part of the install is to drill in he air box. I opened it today and noticed brown residue right below the fitting I put into the hole I drilled. Ran my finger inside the fitting and there was dried brown substance. Anyone know the issue? It's the line coming from the clean side separator into the air box.
Ignore the yellow line this was taken when I installed it. But the red line is the hose connecting to the box where the drainage is being produced.
