Do you happen to know if the running current is higher, which is easy to measure; or is it the momentary starting current that causes the damage?

With the double relay failure on his bike, should he just replace the pump or is there a test he can make?

It is likey the pump is drawing more current when it runs. That fact that it does not run constantly would mean that the higher current is causing damage to the contacts every time it starts. This would lead to faster wear. Really high current would mean very fast wear!
