Tank removal is not required at all. A couple of screws hold the cargo floor down. Remove these, lift the floor and you will see a metal plate with 2 screws that gives access to the intank pump/quantity sensor unit.

In reference to the original question, it is easy to tell if the in-tank pump is running by listening at the open fuel filler. To double check, pull fuse #5 with the engine running and the in tank pump sound should stop.

If it is running, there could still be a leaking hose at the pump output. Pull the pump unit to check (wise to replace the hose at this point). If the pump and hose are OK and the filter sock is clean, accept the noise from the main pump and drive until you notice the engine losing power under conditions of high fuel flow (high rpm and wide open throttle). Degradation is very slow (1000's or 10s of 1000s of miles), so when you notice a problem, you can start to think abpout replacing the pump. It is something that doesn't need to be replaced if it ain't broke.
