Does anyone know how to determine what your Injector Rated Fuel Pressure is? I am trying to use the injector spread sheet.

Injector Rated Fuel Pressure is the fuel pressure which the injector flows 57# (in your case). So in other words, you need to contact Siemens and find out what pressure they flow their injectors at when they test them.

FWIW, its likely going to be 43.5psi, but you still should call Siemens.

The industry standard for rating injectors is 43psi. So usually any advertised flow rate will be based on 43psi.

You would do well not to make any such assumption,
however. There are enough who don't adhere.
