Actually there is more to not installing an oversize pump than just cost. Larger pumps circulate more fuel through the regulator so you need to design the regulator for the increased fuel flow, also because the pump is bypassing more fuel it will heat the fuel more, and hotter fuel means less dense fuel chargers which taxes the fuel system more and robs power. Also larger pumps draw more amps putting more load on the alternator. Ok i guess if you spend enough you can circumvent most of that so it does come down to cost, but not just because the bigger pump costs more.
