Bird & Paul,

Thanks for the reply. It is a hypro model 6500c pump. I flushed with antifreeze when finished a few days ago. Just didn't know if one was better than the other (antifreeze or oil). I only anticipate using it a few times each spring for broadleaf control and wanted to make sure it didn't corrode on me while sitting the rest of the year. Antifreeze seems a little less messy than oil. Thanks again.
