HHR Fuel pressure

Is the low pressure PSI the same on 57-60 on the non-turbo as the SS ?

The fuel pressure is not constant from either pump it is controlled by demand. There is no return line.

That is why they don't really specify anything.

Well dangit, that's not the right link. I was trying to capture 843de stating 50-60 psi on a 2.2, I think it was a 2008.
