⁽¹⁾	Operating fuel line primary pump pressure.

⁽²⁾	Information is not available from manufacturer.

⁽³⁾	With a manual gauge, the fuel pressure will be lower.

⁽⁴⁾	Based on 60°C (140°F) fuel rail temperature, at fuel rail temperatures above 60°C (140°F), for example hot starts, the fuel rail pressure increases based on temperature up to 448 kPa (65 psi).
