Hey Guys, I am a handy homeowner. Tne years ago or so I bought a package with a Porter Cable Pancake 2002 compressor with three nail guns for a project. It has sat in a dry basement since then. I pulled it out yesterday to attached some loose trim and found that the compressor got up to 150 pounds with no problem but I had NO pressure in the hose. Any advice on solving this? Can I fix it on my own or do I need a repair? Thanks much.
