100 PSI PUMP (1 GPM FLOW) FOR M4

Lance demonstrates how to change out the M4 pump with a standard Philips Screw Driver and needle nose pliers in 30 minutes or less. 

100 PSI 1GPM 12 VOLT 4.0 AMP SANTOPRENE DIAPHRAGM PUMP WITH AUTOMATIC PRESSURE REGULATOR. M14X1.5MM THREADED OUTPUT AND 3/8" BARBED INTAKE. FLOW DIRECTION FOR THE TOP VIEW SHOWN IS FROM LEFT TO RIGHT. THIS IS THE CORRECT REPLACEMENT PUMP FOR THE LATEST M4 SPRAYER WITH A BATTERY DOOR. SEE PICTURE OF INSTALLED PUMP.  IF YOU OWN THE OLDER M4 (WITHOUT A BATTERY DOOR), SOMETIMES REFERRED TO AS "MINI",  THIS IS THE WRONG PUMP. (SEE OTHER LISTING)

*******NOTE: REMOVE THE RUBBER INSERTS FROM INSIDE PUMP INLET AND OUTLET BEFORE INSTALLING*******

(THE INSERTS COMPLETELY SEAL THE PUMP DIAPHRAGM AND ARE INTENDED TO KEEP THE DIAPHRAGM WET TO PROVIDE ADEQUATE PRIMING WHEN FIRST INSTALLED.) 

 IT IS RECOMMENDED TO USE THE STRAIN RELIEF HOSE (ATTACHED TO THE PUMP OUTPUT THREADS) IF THE MAIN HOSE IS STIFF. THIS PROTECTS THE MOTOR THREADS FROM BEING BROKEN OFF AND MAKES THE HOSE EASIER TO USE (SEE ATTACHED PICTURE)
