With the vacuum hose removed from the fuel pressure regulator (pinch the vacuum hose so its closed) it should be 38-46 psi. With the vacuum hose on the regulator, 30-37 psi.
If you notice a strong smell of gas with the hose off the fuel pressure regulator, the FPR may have a torn diaphragm and would have to replace it. |
