Today my Fuel Pressure was consistently reading above 7.5 psi and
at one point was reading 9.1. This was at cruise with the Facet
pump off at 45 F. Additionally, it was erratic sometimes as low as
4.5.
I’m flying behind an XP 0-360, MA 4.5 carburetor and EIS 4000 with
standard plumbing. Some time ago I was having low pressure
problems and changed the sensor which seemed to fix the problem.
I’m thinking the sensor is just reading to high.
It doesn’t seem like the engine pump could actually be producing
too much pressure. If it were, does anyone know if there is any
potential harm to the carburetor?
Has anyone else experienced similar problems? What should the
Fuel Pressure actually be? Has anyone got any ideas?

There should be fuel pressure limits in the operating manual for that
engine. How does your observed pressure compare to those limits?
