Hey Clanton I finally got the allen screw out. I had to go buy a 10mm allen wrench. It has a spring with a small plunger in it. Back in it looks like a O-ring with a small hole the spring fits into. I tried to take it out but it didn't want to come out easily. Also when I remove relief valve there is two o-rings and when I look back in it it looks like another o-ring and a small round piece of metal. Any help appreciated. Thanks
