NeighborJ Posted July 29, 2017 Share Posted July 29, 2017 I made my own but it's only a single pump,only 4 parts. Wouldn't be difficult to make one as a gang pump. I'm certain it is not beyond the capabilities of Caleb, Wolter or firesmith to create one. The picture you've found looks elegantly simple and shouldn't be hard to make from the plumbing department at Home Depot and a soldering torch. 1 Link to comment Share on other sites More sharing options...
passgas Posted July 29, 2017 Author Share Posted July 29, 2017 I like how yours is made. I looking to make about a 3/8" dia. This where a 3D printer can come in to play. Link to comment Share on other sites More sharing options...
