Tony has a good point about vapor lock, the Facet won't make that
entirely a non-issue but it helps. I use a twin Facet and pressure
regulator setup for my rotary, and while I can tell you that the
engine sound is wonderful and I love to listen to it, I can also
tell a lot about what's going on from the sound of the fuel pumps.
The sound they make has a lot more high-end harmonics when they are
moving a lot of fuel, and I can compare what I'm hearing with what I
expect. I've found and fixed a couple of problems that way. Also,
when I don't hear them, I know why the engine stopped. The rubber
mounting will help with noise isolation.
