Just swapped out a FNA AAA Triplex 4G/4000 pump for an AR RRV4GD-40 with an external Unloader (looks like a VRT3-310) and want to remove the bypass hose on the unloader.
Anyone have any idea what size Barb’s are on each end of the bypass hose? I obviously have to plug the lower hole with a mnpt plug and put a mnpt Barb on the unliader bypass hose outlet. I want to keep the original bypass hose and Barb’s intact to not in validate the 5 yr warranty AR gives…they look to be 3/8 on the lower and 1/2 on the unloader but I wanted to ask as I know this is a common mod. The whole external Unloader looks identical to the one on Pressure Pros site.
Thanks!
