Hello everyone. I have an equipment question. I recently purchased a 4" party pump part number
7509E. I am going to use the party pump for some testing which will require me to install a spacer in between the 4" chrome plated party pump and the coupler assembly. The problem I am having is finding a spacer of the correct diameter and thread size. The thread size listed for the party pump is 3-1/4"-18 and that is shown
here. What thread size is 3-1/4"-18? Is it 3.25"-18? If that what it is saying it is wrong because when I measured it it was closer to 9/16". Can someone please tell me the diameter and thread size for the male threaded connection at the bottom of the party pump? Thanks in advance for your help.
One more question. What is the diameter and thread size for the threaded portion of the nipple that the beer hose attaches to on the coupler assembly? Also, is that part not replaceable? I didn't see it listed as a replacement part.
