Petcock fuel pump to electric fuel pump?
 

So I have the 139QMB 49cc engine with the petcock vacuum fuel pump and I was wondering if there was any possible way to swap them? Is there any tutorials, or items I could buy?

Sure you can... several video showing how to do it, probably not for your exact scooter but you'll get the ideal.... here's one, .. https://www.youtube.com/watch?v=pZEF9QvxZDI you might want to check the vacuum lines and filter to the existing setup as the stock setup vacuum pump should be plenty good enough.
