besides price, what is the difference between these 2 pumps? Midwest and Oregon fuel injection both sell the high performance vp and they are much cheaper than the Hot Rod vp's. is there anyone out there running one of the (Midwest/Oregon)high performance one's?

 

Are you referring to the II HRVP? I would avoid that pump entirely. Poor manners, and you can go just as far as an HRVP as you will with an SO pump.
