Typical Fuel Pressure?

[boom3]

Wondering what kind of fuel pressure I should expect.

I have an IO-360B1B with Precision Siverhawk servo and Airflow performance electric fuel pump.

Typical setup per the plans, Dynon fuel pressure tranducer line connected to the "T" on the output of the mechanical fuel pump.

I seem to be getting between 10 and 11PSI with the engine running and the electric pump running. This is pretty consistant even at full power.

Thanks!

I found some good info here. I need to make sure my D120 is setup correctly as mine does seem to be too low.

25 to 30 psi is normal for a FI engine.

Thanks Walt.

Looks like I just need to change the sensor type in programming to "injected" as it's probably still on the default of "carburated".

I'm pretty sure that is the problem. My Bad!

I get a steady 23-24 PSI with just the mechanical fuel pump and when I turn my electric pump , it goes to 32-33 for a few seconds and settle down about 27 PSI.
