Errrrrrrrrrr, somethings not right there......im surprised the pump even works I'm totally up on cossie's but i think the pump relay is in the fusebox, trace back to there first and see if the voltage is as low there?

If its a 2wd saph it is a yellow relay with a yellow plug on it
Its behind the glove box on the passenger side of the car
Not sure about 4x4 saphs though

7 volts is well low,be carefull using it with that voltage at pump

There is a thread in the techcnical essays forum on re-wiring your pump m8
