    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....

    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.
