Bought some stainless hose clamps to replace the originals on my new oil lines. These are pretty compact and sized just right for3/8 line. As I was installing the lines and removing the old orignal clamps I noticed the originals have a solid band as opposed to the slotted worm driven new ones. The originals just have the slot for a flat blade screw driver as the new ones have a hex which is why I went with them. But now noticing the difference I'm wondering if I should revert back to original. I'm getting paranoid after returning my miles anti sump valve. Time for a few fingers of #7. Thanx, Rick
