Colin, Some earlier cars were retrofitted with an in tank pump due to vapor lock problems in certain climates. It is very easy for you to tell if you have one. Open the trunk and look at the top of the gas tank for the sender unit. If it has several wires and a fuel hose coming out of it, you have an in tank pump. If it only has wires, you don't. Regardless of the tank pump or lack of one, you will have a main pump under the car in front of the spare tire well. If you haven't replaced the filter between the tank and the main pump yet, do yourself a favor and do it now. They can plug up pretty fast if you have any rust inside the tank. If your filter is connected to a hose coming out of the bottom of the tank be prepared for any fuel in the tank to go all over the place. You can pinch off the hose with a clamp or vice grip wrench, but you may have a flexible metal armor over the hose. In that case I will stick the end of an old spark plug in the end of the hose to plug it while I get the new filter in place. Also if you have any interest in safety you should replace all the fuel hosed with a FI rated hose and FI clamps. Don't forget the two hoses in the engine compartment. The newer fuels are not very kind to old hoses. Look at the bottom of this page http://www.wesingram.com/hp.htm and download the "Fuel Supply Diagnostic Guide" for additional help.
