How long will it last? Well if you mean the pump - could last for a long time - just a bad check valve.
How easy to replace fuel pump? Not hard at all (IMO) I am by no means a mechanic and I have had mine out.
What model is your truck? I have had the box off mine - not a hard job at all but with mine being a quad cab, the fuel pump mainly sits under the cab and not the box. I pulled my tank off the other weekend in less than a half hour - I made sure it was near empty.
It was pretty easy but I have "played" with the tank and tank straps quite a bit before.
If you would like a step by step, let me know.
But if you are thinking of dropping the tank to replace the fuel pump, I would also suggest getting new straps and probably new evap hoses and replace them while you're at it
