I had both the HF and the NT tools pumps and the NT pump is better. They are the same size motor but its the impeller size thats different. The NT is better construction and worth the extra $10 or whatever it is. The HF is a white cast metal, where the NT is actually cast iron.
Sometimes the priming and/or pumping issue is the hole thats cast inside the pump that feeds the impeller is too small or has casting remains it and blocks the flow. I took a dremel tool and ported it out a little and it pumps like mad now.
A word to the wise the pumps are also a bitty to prime if the outlet for the pump isnt pointing straight up. The impeller will never evacuate the air.
