I have to replace the fuel pump on my vehicle listed above (LT model), after searching I have come across a few things indicating there are two fuel pumps. Is that true and if so, how do I know which to replace? I just don't know what to do and need some clarification about it.

Hello, it looks like the pump assembly is one unit, it's a unique design. It is to ensure there is always solid fuel pressure "even during low fuel conditions and aggressive vehicle maneuvers". If there a reason you need to replace the pump assembly?
This is what service information is showing.

Here is the process for fuel pressure relief and draining the tank. And then pretty much all the service information on this fuel system and operations. I don't see any access to the fuel pump assembly, so it looks like the tank needs to be dropped.
There are quite a few Fuel System Technical Service Bulletins, so if you are having some specific issue, it would be good to look that up before dropping the tank.
