Its threaded, right? I'll toss mine in the car tonight- I need to grab some homer buckets Friday for grain splits in a group buy- I'll see if I can match it to anything there- you may be able to make your own replacement...
Yeah, it should be a 1-1/4"which is the threading on the pump itself (from the site) though for some reason they dont even list the part for this particular pump on their site http://superiorpump.com/adapters.html I am just wondering about the threadding. Getting it threadded to the threaded PVC was a little tight as it is.
Thanks!
