Conclusions

• Sulfur changes may coincide with gravity change.
  More supporting data than not.
• Interface size is larger than typical.
• In and out of tankage offer greatest
  contamination problems. Over displacement is the
  only method to protect the ULSD.
• Tests indicate a lower specification will be
  required.
