Meziere Electric Water Pump for Small Block

The Lower hose fitting is 1.80" where the hose clamp attaches around and 1.88" at the front lip of the hose clamp area. The lower radiator hose screws in so other versions or adapters can be fitted. It is also possible to switch the lower radiator hose from side to side as they screw in to the housing. The other side has a screw in plug. The max distance of the water pump to timing cover housing is 6.50". I do not have the other end of the pig tail but that should be available at an auto parts store.
