bypass help needed

I know this sounds like I don't know what I'm doing but is there a solution to this problem?
I have an older intake with the smaller bypass hose and I am using the newer aluminum water pump which takes a larger hose. right now I'm using what came with the intake which is a pipe nipple and a pipe adapter but it looks kinda hokey. do they make a hose with two different sizes, or a nipple for the intake that starts out small and has the larger hose bib?
