How do I get debris out of the body so my nozzle will go in?

Before installing a nozzle into a body that has been without a nozzle for any period of time the line, allow the system to blow the line to eliminate any debris that may have fallen into the line. If some debris, rocks, is to heavy to lift out of the line, place the install tool over the hole to create turbulence in the body cup. This will eliminate any debris in the body cup.
