I actually had to get back in there recently to reseat the pump gasket. I was getting a lot of raw fumes and finally realized the gasket had pinched out a little bit on installation, of course it was just a few minutes to fix it. I did however decide that I am going to do a flange and gasket around the cut...... someday....2008 Silverado LT

I recently replaced the fuel pump on my 2001 Yukon XL 1500 from
the inside. I made an access hole with re-attachable cover. I
only had to remove the 2nd row bench seat and pull the carpet
back(no cutting of carpet required). I used a low depth cutting
wheel, fairly easy, the entire job took me a few hours. Replacing
the pump is easy at this point and self explanatory. Notice the
weld spots above the cutout. There is a stiffener welded under the
floor so the top of the cutout is about 1/2 inch below the welds.
The width of the cutout is 12 inches. See pictures.

I figured I would add where to cut on a Suburban (this is a '99 GMT400).
I used a sawzall and dropped the tank as far as it would go without disconnecting anything. I just undid the straps at the bumper end and lowered the tank with a floor jack using a chunk of plywood to protect the tank. I had a few inches of clearance, but those small hoses near the bumper end were pretty close. A nibbler would work great.
There is a crossmember in there to cut through. I bolted in a steel bar to replace the chunk I cut out. I also laid a large chunk of plywood to protect the hatch when I'm running a load or the kids are jumping around in there.Rob
