Add antifreeze to pump

1. Choose the correct antifreeze

Use either RV antifreeze or a can of Pump Saver.

 

2. Attach Pump Saver hose to the inlet of the pump

If you use RV antifreeze, you'll want to rig up a hose to the inlet of the pump and a funnel to outlet. This will allow you to add the antifreeze to your pump.

If you're using a can of Pump Saver, simply screw the hose from the can to the inlet on the pump.

 

3. Place container over the outlet of the pump

This will catch the excess fluids that will drain out during this process.

 

4. Spray the Pump Saver

Hold down the Pump Saver button for about 10-20 seconds.

Remove all fuel from your fuel system

1. Clamp off the fuel line

Use of pair of hose clamps to clamp your fuel line.

 

2. Release fuel clamp and full fuel line away from carburetor/fuel pump

Use a pair of needle-nose pliers to remove the fuel clamp -- then pull the fuel off of the carburetor or fuel pump (models may be different).

 

3. Drain fuel into container

After you remove the hose from the carburetor, make sure you have a container to catch the fuel you'll be draining.

 

4. Reattach fuel line and clamp

Once all of the fuel has been emptied, replace the fuel line and clamp into their original locations.

 

5. Remove fuel from the carburetor bowl

Depending on the type of carburetor you have, you'll empty the fuel by loosening a valve screw or by removing and draining the bowl completely.
