After 40 hours of fight in New Blue, I had an infight failure of the mechanical pump. It was brought to my attention by a low fuel pressure alarm which was set at 2.0 psi. I didn't really know that it was a failure because the engine never skipped a beat during the next twenty minutes it took for me to get back to base. With the cowling off, I could see that fuel had been coming out of the weep hole on the bottom of the pump. Not a great amount, but it enough to render the pump inop. So barring any failure that could cause a real blockage, the electric pump is more than sufficient to keep the engine running.
