I would run EACH pump from the hot(+) lead, not one source(and then splitting off to each pump).
It may be overkill, but a 0.1uF/16Volt capacitor across each relay located between positive and negative will keep the pumps basically impervious to voltage spikes that may occur to the pumps from the alternator.
