This Scavenge Pipe is for older dry sump pumps that have a threaded scavenge inlet ports. We have never sold this type of pump, but many are still in use. This 5/8" diameter bent pipe has a male 7/8-14 UNF threaded swiveling nut flared on.
Our Titan 5-port pumps use the Clip-Retained Scavenge Pipe (Part No. 167-42), which seals with two O-rings and is held in place with a circlip.
