Reliable sources have already said it will be fine but also think of it this way. If your engine were to used as much fuel as the stock fuel pump could pump there is something radiacally wrong. If it were the case your tank would be empty in minutes.

In saying this I had a stock pump that was a little sick and it started leaning out up high. Bought a brand new one for $50 and I know it pumps heaps. Forgot to put the floats back in the carbs lol
