I purchased this pressure stick from Amazon. Unfortunately, the seller did not provide any instructions etc. with the purchase. I am currently troubleshooting my Polaris 380 - and have reached this stage. However l, I want to avoid making stupid mistakes/errors in setup and found this forum which looks like it has what I am looking for: educated sound advise. Now, correct me if I am writing here - but should there not be some type of nipple here er adapter to accommodate my pressure-side hose? Things like that, Thank you all in advance. Question: how do I properly use this?
