What is the max fuel pressure I should see on my O-320 B2C with mechanical pump only and then with both mechanical and electric?

Thanks,
Duane
 
Duane,
My 0-320 runs around 3.5 to 4.0 psi mechanical, and about 4.5 psi with the boost pump on (as displayed on Dynon EMS).

My 0-320 reads 4.5 psi mech pump only and 5.3psi with electric on. Readings are from the dynon 180.
 
Lycoming says: 8psi max .5 psi min.
Good Luck,
Mahlon
