  • The aerated bunkers when sounded will give the impression that the fuel is delivered as ordered, when in fact when the entrapped air in suspension settles out of the fuel oil the oil level drops, and a shortfall is discovered.

  • Bunker hose jerking or whipping around
  • Gurgling sound when standing in the vicinity of bunker manifold.
  • Fluctuations of pressure indication on the manifold pressure gauge. Unusual noises from the bunker barge
