Right, but we were talking about gasoline fuel injection, which generally runs much lower pressures. I'm only really familiar with the Bosch systems, but they ran about 30 psi for L-Jetronic and its derivatives, and about 90 psi for K-Jetronic (aka. CIS). I don't know what the new direct-injection systems are running. It would have to be higher to overcome the cylinder pressures.
