You will lose 20 PSI from the 45' elevation. A booster pump is needed. I assume the booster pumps are not lasting long because they cycle on and off too much or you are using that "all in one, easy/peasy, type pumps that are made to sell, not to last. Get a good jet pump like a Goulds J10S and control it with a Cycle Stop Valve like comes in the PK1A kit and you will have a pump system that will last a lifetime. As long as the meter can keep up with demand and not starve the pump, it will last decades. If it does draw the city line too low, a small cistern for the booster pump to draw from can solve that as well.
The reason pump companies do not offer a Cycle Stop Valve is because it is a disruptive product that makes pumps last much longer, and they like selling you 3 news pumps in 8 years.
BTW, a submersible makes a good booster when drawing from a cistern.
