I think it needs to be a diaphragm pump. Many "self priming" pumps actually need fluid in them to work. I used a ShurFlo pump that I purchased online for $80+shipping (I have Amazon Prime which includes free shipping) and it worked well for me. One of the diaphragms did fail after three weeks but the replacement is $15 and I don't think that is a bad price to add vacuum.
