If a pumps starts to fail via low output or there is a clog in the filter or elsewhere in the system it will manifest with decreased flow but maybe not in the fuel pressure. Interesting use of a flow sensor. Since the filters are such a pain, and mess to change, I was thinking of doing a test where I just ran the fuel into a jug to measure the time to flow 5 gallons. If I do this while the filters are very low time, I could use that as a way to tell when they need to be replaced. It's likely they don't need to be replaced very often. I hadn't decided if I was going to pursue such a test or not though.
