I now how 35 hours in my RV14A with the IO-390. First 32 hours were perfect and the EFII system (Fuel Injection and EI) has been great, very very smooth. Starting a few hours ago instead of seeing a slight decrease in fuel pressure (28.7 in. mp and 42 psi) at I take off and slight decline when in cruise (22.0 in. mp and 39 psi) and now seeing at take-off 29 psi and 34 psi in cruise. Idle still around 40 psi. I have not contacted EFII yet and will try tomorrow. (Robert has been extremely helpful this last 3 years during the build and engine run-up) Checked the fuel flow and it's ~ 50 GPM ok. (35 GPM min.). Seems the filters must be ok. (It has a pre-pump filter and a post pump filter) The regulator is plumbed per instructions and the mp line to the regulator appears to be fine. Any suggestions?
