anyone ran this pump or have any specs on it. planning to build a nice water inj system and looking at pumps

Thanks
 
Coming from holley, it's probably a good quality piece... Price is right too.. Details like pressure/flow are tough to find... Maybe contact Holley and see if they'll fill you in?
 
shureflo makes all kinds of pumps. you'll need to find one that suits your needs.
