Thanks! I have been reading the links provided . . since the tank has been empty for some time, should I assume that the pump is now shot? Also, car sits a little low in back, in fact, felt surprisingly good on the road - is it true that springs need to be replaced if this is the case? Seems odd that this would be as the literature states that the car is designed to ride on springs only when car is unladen in the rear? What gives?
