Is it easier to change a fuel tank complete with pump than just changing a fuel pump on a 1993 Buick Century?

It%26#039;s a wash, because you have to take the tank out to put in the pump anyway. You should probably just get the pump and put it in so you don%26#039;t have to buy a tank too. Save some money. Unless the tank is rusted through, but if it ain%26#039;t broke, don%26#039;t fix it.|||same..u drop tank..replace pump...or drop tank..put new pump in new tank ...and replace...|||Since the tank has to be dropped to access the pump there really is not much difference. However if you just replace the pump there are about eight screws to remove around the pump sealing gasket. I have a sneaky suspicion that you have worded this wrong and mean to replace the pump and tank sending unit instead of pump and tank. Then the easiest would be to replace the whole unit.|||I%26#039;m guessing that a 93 century probably has a pretty rusty tank depending on where you live. If it is, and it%26#039;s leaking, you probably have to replace the sending unit assembly anyways because the lines are probably rusted up pretty bad where they come out of the sending unit and attach to the vehicle. Either way, If you use gm parts,and I highly suggest that you do unless you like dropping the tank to change the pump, the sending unit will probably come without the pump on it. You%26#039;ll probably have to order the pump separate. If you were to change the whole tank with a pump already installed, there is no way I would use the pump that%26#039;s in there. No telling what shape that pump is in. If the tank is not rusted and leaking, don%26#039;t replace it. If the sending unit lines are not rusted off and leaking and you can get them loose with out breaking them, then just replace the pump. It%26#039;s not that hard. but like I said, the lines are probably going to be rusted and will break upon trying to loosen them so I would plan I buying a sending unit along with a new pump. A complete assembly with a pump included is probably available in the aftermarket, but aftermarket pumps fail far too often to not go with OEM.
