I recently have become aware of a need to watch my fuel pressure on climb. I have had some interesting readings of late and wanted to get some feedback/thoughts etc...
Engine: Thunderbolt YIO-540, Airflow Performance Fuel Injection
Today I completed a max altitude, with a new oxygen system test and kept an eye on my fuel pressure. Basically it continued to drop from initial of 26 psi down to 14 psi at 11,500 feet. I flattened out for a small time and it jumped back up to 22 psi then it dropped back to 14 psi when I recommenced my climb.
My climb rate was not excessive, 500 fpm. So I switched on my electrical pump and got it back to 27 psi.
After achieving 19,500 I flattened out and switched off my electrical pump and it settled back to 24 psi.
I am wondering if this appears normal, or if this seems a little "under done".
Eager for thoughts.
BTW FYI: OAT was 23 Celcius...
