I recently replaced the relief valve located on the On/Off switch box of my compressor but air continues to leak.

Chances are the relief valve is not what's causing the leak. The check valve located on the tank may be the culprit (see image).
Turn pressure switch to OFF position.
Unplug the compressor from the outlet.
Drain air tank by loosening the drain valve located on the bottom of the tank (see image).
Remove the check valve located on the tank (see image).
Check rubber grommet inside check valve for cracks/breakage. Replace if needed (conveniently order parts from our easy to navigate e-store).
Install new check valve using Teflon tape.
Plug compressor in and turn air compressor to ON position.
Check for leaks.
