Would have been 5 stars but for one observation. The filter did not come with the oring between the filter and regulator. I should have noticed but did not and assembled and installed the assembly, unknowingly, without the oring. Of course, the pump would not hold pressure so the assembly had to be pulled back out, disassembled to realize the missing oring was the problem. Sourcing the oring delayed the re-assembly. As I said, I should have noticed the oring was missing but I do think the filter should have come with the oring in the kit, preferably installed but at least in the kit.
