Knowing that "access" doors exist on other vehicles for the fuel pump, the concept of adding an access door itself doesn't bother me. The absence of one originally may be simply a cost savings measure.

That said, I'd have to agree that draining and dropping the tank probably takes less time than to strip the interior, carefully cut through the floor, cut a new larger patch from a junkyard Tahoe, drill, prime, and install the patch. The patch should have been sealed with a butyl sealant as well to prevent any exhaust vapors from entering the vehicle. Also, this job is likely to be done only once in the lifetime of the vehicle.

I believe these tanks are quite light once the fuel is removed.

The time it took you to do that could have had the tank dropped and back in...

This mod could be a lifesaver if your pump failed far away from home like a road trip or camping trip or even during a blizzard.


My reasoning about why I do not agree with the access is documented and does have to do with physical harm.

Here are photos showing the location of a DIY access hatch for 2007 Yukon XL fuel pump. Its basically the same location as in the pre-2007 generation. Used a Dremel with a metal cutting wheel. Was super easy. Yes it created sparks, but there was zero issue with the sparks igniting gasoline. This was MUCH easier and faster than dropping the fuel tank and havingView attachment 233668 to disconnect all of the hoses and vent lines. View attachment 233669 View attachment 233670
