ELECTRIC FUEL PUMP PRESSURE SPECIFICATION
| Instrument | Specification | Measurement |
|---|---|---|
| 0-1.1 MPa (0-160 psi) gauge | 310-379 kPa (45-55 psi) minimum |
If pressure fails low, go to step 10b .
If fuel pressure is above specification, check fuel return lines for restriction.
If no restriction is present, install a new fuel pressure regulator valve.
