As a fleet owner who only buys GM trucks I must dispute this. If I only had one or two I wouldn't pay any attention, but I haven't replaced a fuel pump in DECADES of owning quite a few Savanas and Silverados.
Well with all due respect you must be the luckiest GM owner around. From what I saw of my 4 years over at Trailvoy it seems to be a fairly common failure item and also in my decades of working on cars I have changed quite a few GM electric fuel pumps.
The most recent one was a family member's Astro van. They bought it new and the pump died around 100K or about 5 years. The cheap replacement pump (which I try to convince them not to buy) lasted about a month longer than the 1 year warranty.
At Trailvoy most people replaced the pump assembly because either the pump failed or the sending unit on the pump assembly quit. For most of us it was between 70K - 100K miles or about 5 years but there were some people that had problems around the 35K mile mark. Yes you can replace the pump itself but most of us just bought a new assembly that included the pump since it was a pain to drop the tank.
I'm not trying to bash GM here just stating what my experience has been. On the other hand I used to tick a lot of people off over at Trailvoy when I mentioned my 16 year old Ford van with over 200K miles still has the original pump and works greats!
Edit: Also GM had a recall on the early model SUV's (2002-2003 Trailblazer, Envoy, Rainer, Bravada) In areas where they had a lot of snow, the top of the pump assembly would rust through and leak fuel.
