My fuel pump went out, and am now replacing it using the instructions that I found on this forum. One thing I haven't found mentioned here, is that the fuel pump that I just purchased from Ford is designed a little different from the old one. The old one is exactly as described in this forum, but the new one attaches different. Instead of it fitting down into the lock ring in the bottom of the tank, the new pump is hard attached to the top access plate. The bottom of the pump has 4 rubber pads that is to rest on the bottom of the tank. If anyone is familar with this change in design, my question is, do you have to remove the old lock ring in the bottom of the tank to install this new pump? That lock ring is attached to the bottom of the tank with 4 molded tabs that would have to be cut off to get the ring out. The enclosed installation instructions with the new pump says Ford has a special tool to cut off these tabs and remove this ring. Is this necessary to remove this ring, or will the new pump sit down on this ring with no problem??? I'd rather not have to try and find this special tool, unless absolutely necessary.
