So my car was working fine, actually ordered the same membranes a year later and again decided it was time for a replacement. I put both in, it doesn't flow from one membrane, I put the old one back in, it flows a lot. Switchable housings, no flow. Okay, the diaphragm must be clogged. I ordered a replacement from Amazon. Throw one, but there is no flow. The second I opened well, threw in and flows normally. As far as I can tell, I clogged two membranes, I don't know how this is possible, but most likely I will not order this brand again.
