First test start went great, had to pull the fuel hanger back out and squeeze in a 6th stud since I found out the fuel temp and fuel level sensors are separate circuits, not common ground.
Threw a bunch of 93 in the tank, wired up the pump, threw on my gauge to read fuel pressure then bumped the FPR up a couple turns to hit 500kpa that the Q50 FSM calls for.
These direct injectors are incredibly loud in the garage with no hood and no engine cover, it almost sounds like a diesel. At least the Bosch 044 is pretty quiet inside the tank now.
