This kit will convert your VHL tank internal submersible pump to ANX series external pump.  With the external pump you can add an auto shutoff DEF nozzle or use the self loading pump adapter to pull def from external tanks or the 22 mod auxiliary tanks to expand capacity.    Kit comes with an ANX pump, mounting screws, wire harness and pump adapters to mount on the top of your existing tank.   The internal pump is removed and the internal discharge hose becomes the suction tube.  Pinch clamps are supplied for new hose connections.    Self loading hose adapter and auto shutoff nozzle sold separately.
