its one of the Moroso HV race pumps. the one that was on it before was a Melling HV pump. being honest here when you set the $29.95 melling pump next to the $79.99 Moroso pump visually they look identical. Casting numbers are even the same. when you tear them apart you can see that Moroso Deburs everything and changes the bypass set up. Keep in mind 2 pumps, same problem. both were new.
