I know Cobalt's fuel pump is in tank and the rails can run up to 2800psi. So if it can push 4 cylinders to 30psi then it should be able to push 6 at 5-10psi.

Hopefully this can help solve the puzzle
Actually the Cobalts have a similar setup to ours. The in-tank low-pressure pump and a high-pressure pump connected to the cam shaft. They have exactly the same pump and had to rely on aftermarket manufacturers to build new high-pressure pumps. That's what we are working on now.
