I should've posted an update to this.
Well, you're right about the light being a restriction in flow, but it doesn't necessarily mean that the fuel line is clogged. The screen is on the return line, which shouldn't cause the light, as it would make the pressure higher than needed, rather than lower than needed. Along with blowing out the fuel lines with compressed air, I the screen was well cleaned out before this happened--this was part of an extended-duration "issue" shall we say. I also had to do the fuel pick-up inlet screen(broken) before I posted this problem. I had fixed the problem (a hole in the suction line, sucking lots of air bubbles into the fuel bowl, eventually draining it completely) but my repair (a new hose clamp) ended up splitting the flex-line that I should have completely replaced instead of cutting off the end, and wound up causing a bad fuel leak, and air in the fuel line. It was my own fault. I was just trying to keep from replacing the whole section of flexible hose. I ended up having to replace it, as well as the fuel tank selector valve, also known as the pollack valve, because I broke it pulling off the damaged flex-line. Seventeen years of diesel through the valve made the plastic VERY brittle. Expensive lesson learned. All better now.
