Airplane - F1 Rocket, IO-540 D4A5, recent install of Red Cube between fuel servo and spider. Engine driven fuel pump has ~350 hours.
Pulling 3 g's at the start of a loop I am experiencing a fuel pressure loss from the normal 20+ psi to ~8 psi (engine loses power) after which my boost pump automatically kicks in (power picks back up) and brings the pressure back to normal.
I can fly around all day, pulling 2 g's in 60* banks, and no issues, fuel pressure stays 20+ psi.
Anybody experience the same? Am I correct to assume a new engine driven fuel pump is in my near future?
