You might not like this one, but if by looking under the hood you haven’t found the fuel pump you might want to have someone else do this for you.
I think that the OP is more on-target than you are. While the mechanical fuel pumps of yesteryear could be found under the hood, modern-day electric fuel pumps are usually found in the gas tank or directly adjacent to it.
Perhaps my first post was not clear enough. The fuel pump on this car as well as most late model fuel injected cars is in the gas tank. The gas tank does not need to be removed for replacement. There is an access panel located under the rear seat. The removal and installation instructions I posted are straight from the repair manual.

The fuel pump is a $300 item. Why are you changing it? Are you changing it to see if it fixes a problem? If you are, that’s a very expensive troubleshooting technique. What if changing the fuel pump doesn’t fix it? The next expensive item is the engine computer. A 1999 vehicle can easily have a dirty fuel filter which would slow fuel flow and drop fuel pressure. Have you actually tested the fuel pump AFTER changing that dirty fuel filter? It could be cheaper to let a (good) mechanic test it, first.
Dartman–Your post was exceptionally clear and gave a huge amount of good information. I was replying to Galant, who is apparently unfamiliar with the placement of an electric fuel pump, which coincidentally exists in his own vehicle!
Point taken, I guess I misread the original post. After reading it again I see that the question is not about the location of the pump-my bad.
On the side, I have once fitted an electric fuel pump next to the gas tank in a car that had a mechanical pump that we could not find the replacement for. This was way before the newer designs were out.
I’m having trouble getting the rear seat out of a 99 Sephia to change the pump, any Idea where the screws or bolts are?, don’t want to break it
If it like nearly every other back seat for the last 30 years, there are no bolts. Just clips under the right and left front of the seat. Push down, then back, then lift and pull. Should come right out.
