I've been searching through the forums but was not able to get a clear answer to the exact location of where the stock fuel pump location is.
For a 1999, where would the stock fuel pump be? Is it towards the front of the car or closer to the trunk of the car?

Picture of fuel pump closer to the trunk.
To clarify (for future searchers)
1993-1998 F-Bodies = Metal tank (fuel pump is located towards the front of car).
1999-2002 F-Bodies = Plastic tank (fuel pump is located towards the trunk of the car).

^ the write up doesn't help the question at hand.
I'm guessing the fuel pump's location is different depending on if you have a plastic or metal gas tank.
To the best of my knowledge, I think it's the 99-02s that had the plastic gas tank and if your gas tank is plastic, the fuel pump would be located closer to the trunk portion (anyone willing to confirm).

It is just my opinion, but in all honesty if you are doing the fuel pump on a almost 13yr old car, i would just take the few extra steps and drop the tank, and clean that bad boy out while your at it, over the past 13yrs you dont know what good stuff might have accumulated in it, and if you are putting in a brand new pump, you never know what it may start to suck up outta that tank. Thats just my .02cents thought, Good luck!

I figured I'd add pictures of how I did it. I eyeballed mine and cut it with a Dremel, and I had the perfect amount of space to work. To seal it back up, I bent the flap back down and sealed it with some leftover Quick Roof from an audio install... No hump, no gas smell... PERFECT.

This link pretty good too.

IMO this tool is by far the best to use when cutting the hole. I picked one up at Harbor Freight for less than $20.

You do not need to cut up your car. I replaced the fuel pump in mine in one hour and fifteen minutes. Dropping the tank is no big deal. I had the car up on lift and a friend helped me lower and lift the tank. You don't have to drop the rear end either. Replacing the fuel pump is not a big challenge on these cars. Just get the car up on a lift and do it.

I agree that it's probably easier and quicker if you have access to a lift and a friend who can help lift the gas tank to the ground (cussing also that the tank is nearly full of gasoline).
We seem to forget also, that if the fuel pump is not operating, that the car is not driveable and requires a tow.
The fact is I don't think many (perhaps a majority) of people have access to a lift. Where are you going to find a shop that will rent you a lift, drive your own car onto their lift, raise the lift, let you work on your own car, bring your own tools, and bring along your own parts?
Because of the above, I'd venture to say that a great majority of people on this forum work on their cars in their own garage or in a friends garage with few of us having a lift.
In fact, it's getting so bad in some shops, you have to have permission to even walk out on the shop floor without an escort or have to have key to open the door to the shop.
For most of us, one size doesn't fit all and as a result we have to find ways to accomplish the task at hand with what tools and equipment we have at our disposal and can afford.
Would I liked to have had a lift when I removed the rearend a few weeks ago? You better believe it. But I don't, so I had to do it on jackstands - alone and I'm 65. Sometimes you got to do what you got to do, even though it's not the preferred method.

dlandsvZ28 Congrats to you sir for reaching 65 years of age. I am also 65 years old. Been hot rodding for about 50 years now. Just a FYI for you. You can drop the tank without a lift and you do not need to drop the rear end without a lift either. That is just doing unneeded work. I'm sorry that in your 65 years that you have not met any buddies that will lend you a helping hand for a job like replacing a fuel pump. I just was lucky enough to be able to use a lift to perform the job. Believe me I have done just about any kind of wrenching job on jack stands. I've changed engines, transmissions, and rear ends at numerous race tracks around the country back in my NHRA class racing days. But that is another story altogther. I am sure that a man your age has heard that sometimes it is "who you know" that makes life a little easier. Nuff said.

Kinda like saying, it's easy to do your own open heart surgery, just invite you surgeon neighbor over
3/4 little cuts is no big deal. GM shoulda added the panel to the body stamping. Them being dummies is why we are forced to cut.

I cut mine like the 1st pict posted. Then installed a 1/4 thick piece of stainless steel with self cutting sheet metal screws. I also used a rubber seal over the edges of the hole so IF I ever need to replace, upgrade, whatever, it will be a cakewalk. I made the hole a little bigger just to make it easier to move things around and real glad I did.
