I can't give specific advice on this engine but I like to do preventative maintenance on mine too. Definitely make sure the car is regularly serviced, mine is over serviced if anything.
You could change the pump for peace of mind. Or speak to tuners such as darkside developments, Revo or Celtic tuning to see if they can advise on an upgraded/heavy duty fuel pump.
You might find your pump or similar variants are fitted to other vehicles.
