On my 2007's P/S reservoir the head of the suction line's Ideal clamp / worm-drive clamp / jubilee clip was rubbing against the return line to the point where the fabric was showing through.

All that was needed was to loosen the clamp and rotate it a quarter turn. In my case the head now points straight up. It touches nothing.

I will keep my eye on the divot worn into the return line. Maybe, being low pressure, the thing will be OK.

Otherwise, every inch of the system I can see is bone dry-even the reservoir's neck.

Go check yours--right now.
