I have a 1990 suburban (square body ) that I need to remove and replace the in tank fuel pump. I am considering an access panel in the floor of the bed. it looks as though this is possible but a bit tight due to the support member spacing. The pump is centered between supports but the two line connections are under a support by a little bit. Has anyone made the change out using this method rather than dropping the tank? I am not concerned about reinstalling the cut out. this is an old work rig and would always be covered by the bed mat. I have seen many you tube videos of making access thru the truck bed but not specifically a square body suburban.

looks like I hit the create post button 3 times, sorry about that. I will reinstall the cut out with some tabs and sealant. It will be under the bed mat so not concerned about that just dont want to cut it if I am not going to be able to accomplish the replacement.

A friend of mine replaced the pump on his ‘90 burb through an access hole, so yes, it can be done.
