1.  Disconnect or cut the washer hose between washer pump and nozzles as close as 

possible (no closer than 2”) to washer pump. 

2.  Insert one check valve in-line (washer pump side) making sure the gray side is pointing 

away from the washer pump.  

3.  Attach a 2” section of the supplied rubber hose to the outlet of the one-way valve. Attach 

the supplied tee to the other end of the hose.  

4.  Route a section of the supplied rubber hose from the other end of the tee to the Hotshot 

inlet.  

5.  On the washer reservoir, drill a 5/16” hole in the filler tube about ½” from the top and 

install the supplied rubber grommet in the hole just drilled.  

6.  Open the washer reservoir cap and insert one end of the hard plastic hose down the filler 

tube of washer reservoir. Cut the end of hose that will descend to the bottom of the tank 
at a 45° angle ensuring it is at least 1” shorter than the depth of the reservoir. This will 
prevent the unit from sucking in debris at the bottom. 

7.  On the inside of the washer reservoir filler tube, connect one end of the 90º elbow to the 

top of the hard plastic tube and push the other end of the 90º elbow through the 5/16” 
rubber grommet installed in step 5. 

8.  Connect a 2” piece of the supplied rubber hose to the end of the 90º elbow that was 

pushed through the rubber grommet. 

9.  Connect the other end of the 2” piece of rubber hose to the remaining one-way valve with 

the gray side pointing away from the washer reservoir.
