Where is fuel pump locate

It's in the gas tank. If you've never pulled a tank off to replace a pump, I advise you to buy a Haynes or Chilton repair manual for your Olds to follow the procedure-not immensely difficult, but pretty involved. All lines to the tank removed, electrical plugs disconnected, filler hose removed, then lower and drop the tank-2 straps usually hold it up-(helps to have as little gas as possible in the tank, or it will be quite heavy-in that case, use a floor jack with some wood padding to avoid denting the tank), remove tank away from car. To get to the pump, remove the locking ring (on top of tank) with a brass punch or wooden dowel (so no sparks, see?) or be very careful if you use a steel punch or big screwdriver-NOT RECOMMENDED-but I have done it without sparks, so just be careful. pull the locking ring off and pull out the pump and fuel sender unit. Take off old pump, and replace with new-hopefully it is a OEM-original equipment manufacture-Aftermarket brand pumps just do not perform as well as original (olds) equipment. If the pump has failed, it is good practice to also replace the fuel pump relay-a failing pump can sometimes damage or shorten the life of the fuel pump relay, or so I've heard. Common tools and ratchets are needed for the job-possibly also a release tool for the fuel line fittings-if you have those types of fittings, I think you do, called quick connect fittings.
There's lots of other procedures to get the tank off-like lowering tank, then remove lines and electricals from top of tank, probably the exhaust will have to be lowered, you can siphon gas out the filler neck after lowering the tank a bit. You need to know how to relieve fuel pressure before disconnecting lines, but if little or no gas is in the lines, there won't be pressure. You just need a repair manual to do it step by step-...and label all lines removed, so you know where they go back on the tank.
If I haven't discouraged you yet, buy the manual, and get set for a dirty Saturday afternoon. Essentials like beer and pot are a given. lol.

Where is my fuel pump located

The fuel pump on your particular vehicle is located in the fuel tank. If you plan on replacing yourself, here are the steps to replace it.(You might want to have the gas tank as low as possible for this). 1. Disconnect the battery. 2. Raise and support the vehicle on jack stands. 3. Loosen the fuel tank straps to their lowest point.(Do not remove them completely yet). 4. Disconnect all electrical connections and any lines, including the fuel filler neck. 5. Remove the fuel tank straps and lower the tank. It is recommended to have someone help you, if not use a jack and some blocks to lower the tank. 6. With the fuel tank out, remove the ring keeping the fuel pump secured. 7. Disconnect electrical connections to the pump. 8. Installation is reverse if removal. I hope this helps.
