Fuel pump location needed

Hi and thanks for using 2CarPros.com.

The fuel pump is in the fuel tank. I believe the tank requires removal. However, under the rear seat, there is a large plug that can be removed. I believe it is only for the level sensor, but confirm that. It has been some time since I had one of these in my shop for repair.
Here is a link that shows general directions for pump replacement:

Here is a link that shows how to check a fuel pump (if needed):

Here are the specifications for pump pressure:

Curb idle, 38 PSI

Curb idle w/vacuum disconnected, 47 - 50 PSI

I have attached a picture of under the rear seat, where the plug is located. Also, I attached an exploded view of the tank and its components. It should help if the tank needs removed and as I mentioned, I feel confident it does.

Let me know if this helps or if you have other questions.

Take care,
Joe
