If that's the case, 3 or 4 wraps of teflon tape will probably stop it. The entire threaded part of the pipe should be covered. (In other words, you should still see tape after you've screwed it down snugly) I think some folks might even use more tape but I normally stop at two, sometimes three wraps.
Yeah, it's at the threaded connection. I tried teflon tape, two/three wraps--no go. It doesn't look like there had been anything other than that on it before, though. I found an o-ring, put it over the male end so that it sits where the grey fitting connects to the pump housing--still leaks, but much slower. Should I try again (this weekend, when it's COOLER!) with the thread sealant?
