[QUOTE="TenOunce Tone, post: 7748, member: 288"] Looking at the hydraulic hand pumps on line and in the local mining shop, the arrangement of the collection tube is as GM has indicated, the length is also a lot shorter, maybe 10% of the actual draw length. I would think the flow would go across the sharp side of the elbow.. that way the heavies will fall onto the rounded section, the overburden would flow to the outlet side, sure some will end up in the collection tube but hey, it will be nearly all heavies in there. I have also seen similar items with clear collection tubes, i guess you can see how effective your crevicing is going.. [/QUOTE]
