Volume
Monitor the fuel pressure for 1 minute.
^ If the fuel pressure does not decrease greater than 34 kPa (5 psi) within the specified time, replace the fuel pump module.

Relieve the fuel pressure to 69 kPa (10 psi). Verify that the fuel pressure does not decrease greater than 14 kPa (2 psi) in 5 minutes.

If the fuel pressure decreases greater than the specified value, replace the fuel pump module.

Operate the vehicle within the conditions of the customer's concern while monitoring the fuel pressure with the CH-48027-100 . The fuel pressure should not drop off during acceleration, cruise, or hard cornering.
