SYSTEM INTEGRITY CHECK
- Visually inspect the complete fuel delivery system, including fuel tank lines, reservoir, filter, pumps, injectors, pressure regulator, battery, electrical lines and connectors for leakage, looseness, cracks, pinching, kinking, corrosion, grounding, abrasion, or other damage caused by accident, collision, assembly or usage.
- Verify the the battery is fully charged.
- Check the engine fuse integrity.
- Check for sufficient fuel in the fuel tanks.
- If the system is free of any evidence of leakage, damage, or any other cause for concern, continue with the pressure test.
