The xio360 (9:1 compression 190hp) engine in my RV7A is showing primary fuel pump pressure inflight of from 28.5psi to 35 psi. On shutdown the fuel pressure remains at 28.0. These readings are taken from the EMS side of my Dynon D-180 and DSAB transmitted to my D-100 which I use as my primary EMS. POH shows maximum fuel pressure is 25psi and normal operating at 20psi. I've been operating the engine at these fuel pressure readings now for about 80 hours.
Questions:
1. where can I take a fuel pressure (direct reading gauge) with my engine running?
2. If the (over 25psi) reading is correct, is the high reading a concern? (damage or engine failure) ?
Thanks
