You guys are way over-thinking this filter thing....
Re: "ANY reading not zero and it’s time to change."
No...it's not that simple. In a Racor 900/1000, you have three filter choices, 2 micron, 10 micron and 30 micron. Noting first that you MUST be running under load before even looking at the vacuum gauge, a brand new 2 micron filter will show about 2" when running at 2-3gph. As you might expect, the 10 micron will show less than that and the 30 micron will show the least.
Re: "you can see the level of crud in a Racor in the bowl."
No, because the bowl is on the supply-side (pre-filter), so it can't tell you anything about the condition of the filter media. The bowl is there to capture (and show you) if there is water in the fuel. If you see crud in the bowl, something is very wrong, and has probably been wrong for a long time.
Re: "If the engine slows uncommanded under load, flip the lever."
This is great if you have one of the (totally awesome) dual-Racors. I bought one for our Mainship. Most us (including OP), have the single Racor and there is no lever to flip...
