Just wondering is the later style unloading valve (with o-ring) can be substituted for the early style (metal to metal) Thanks

Quoting Removed, click Modern View to see

TBOMK, you can't use O-ring on spool designed for metal, but if you swap to newer spool with O-ring, it will work.

Thanks, that's exactly what I needed to know. This thing's been giving me fits. Keeps bobbing under load. Hope this fixes it.
