rmaynard 14,888 #2 Posted April 27, 2016 I don't know if there is a diagram, but I have one that I can take apart and get you some pictures if it will help. Share this post Link to post Share on other sites
rmaynard 14,888 #3 Posted April 27, 2016 (edited) Raining here today, so I have plenty of downtime. Took some pictures for you. Here is the vacuum operated (pulse) pump assembled Notice the IN and OUT markings on the top With the screws removed, the pump splits open revealing the diaphragm. With the diaphragm removed, the one-way valve assembly is seen. One screw is removed and the valve cover is removed. Notice the INLET side (left) has a fine coil spring, and the OUTLET side (right) has a flat disc. There is also a gasket to seal the cover. On the left we see the INLET disc, and on the right we see the OUTLET spring. That is how it supposed to be assembled. I hope this helps.
