You mean 8 vein.
You want an 8 vein pump.
Also, if your going through all this, why not put on a new or rebuilt pump ? They are generally, not a lot of money.
I've also seen a lot of these rebuilt wp built with stamped impellers instead of cast impellers. The stamped ones appear like they would move a lot more fluid but they are bad news. They create a lot of cavitation.
