         9 . The apparatus of  claim 1  wherein the downhole tool comprises a fluid pumping system configured to pump fluid into at least one of the first and second fluid ports. 
     
     
         10 . The apparatus of  claim 1  wherein the downhole tool comprises a flow line configured to provide fluid communication between the first fluid port and a location of the wellbore different from a location of the first fluid port. 
     
     
         11 . The apparatus of  claim 1  wherein the connector is configured to provide one of a male-male and a female-female connection. 
     
     
         12 . The apparatus of  claim 1  wherein the first unit and the second unit are interchangeable. 
     
     
         13 . The apparatus of  claim 1  wherein the first unit comprises a unitary mandrel, and wherein the first fluid port is located on the unitary mandrel. 
     
     
         14 . An apparatus, comprising:
 a downhole tool configured for conveyance in a wellbore extending into a subterranean formation, the downhole tool comprising:
 a first unitary mandrel having a first fluid port configured to provide fluid communication between the first mandrel and the wellbore; 
 a second unitary mandrel having a second fluid port configured to provide fluid communication between the second mandrel and the wellbore; 
 a connector configured to connect a first connecting end of the first mandrel with a second connecting end of the second mandrel; 
 a first packer element mounted on the first mandrel and not located between the first fluid port and the first connecting end; and 
 a second packer element mounted on the second mandrel and not located between the second fluid port and the second connecting end. 
   
     
     
         15 . The apparatus of  claim 14  wherein the first and the second mandrels are interchangeable. 
     
     
         16 . The apparatus of  claim 14  wherein the connector does not comprise packer elements. 
     
     
         17 . The apparatus of  claim 14  wherein the connector is configured to provide one of a male-male and a female-female connection.
