If it isn't broken, don't fix it but definitely cut the access hole through the floor of the bed while you've got the tank dropped. Basically straight behind the striker latch for the bench seat. Had to replace mine about three years ago and didn't cut an access hole after that repair. Should have learned my lesson since the bolts had to be torched off to drop the tank. Hindsight is 20/20 I guess. Replaced that same fuel pump again about four months ago. After seeing the work that went into dropping the tank, I wasn't comfortable doing it myself and my mechanic put in what I then discovered to be a cheap pump. Dropped the tank again, put in another fuel pump.
Moral of the story, cut the access now and save massive headaches in the future. I never thought I'd have to replace the fuel pump just three years later and got screwed by my shortsightedness.
