HomeLite AP-320 Water Pump 3hp
UsedBuy It Now

HomeLite AP-320 Water Pump 3hp

Homelite 3hp trash pump with Briggs and Stratton engine, this pump runs but surges a bit (doesn’t hold a specific rpm well) so it will need some carb work. The starter recoil doesn’t rewind all the way either without some help. Long story short, if you’re looking for a super reliable new out of the box pump this isn’t for you. If you’re a fan of homelite vintage equipment and you like restoration then this may be a good option for you.
