The size of the hose is pretty important, as is the length. Probably should be at least 3/8 hose not extended beyond 8 feet. Otherwise, would need to move up to a larger hose diameter.

You might want to consider getting an impact wrench. This pulsates or pounds as it turns and is good for removing large, highly torqued nuts.
