Here you are buying a New Genuine Meyer E57H Plow Pump. These are pulled out of New pump kits. This is the H model pump - 2" taller than standard height pump. The tank measures 8". These were used on the Meyer MDII, Plus mount, and Diamond plows. This uses the better 2 post motor. If you are upgrading from an E47, you will need the extra ground cable. This also has the newer angling block where the male couple comes out the side of the block. Make sure you check all these things. If you have an old style block now, you should get a set of couplers to match this new style.
