Pump is inside the tank, top of tank are rubber lines. From the top of tank all the rubber is accessible from the rear fender well. That is where the metal lines start running so you should not have to remove the tank. Doing the tank is quite a job and I would say that 2 people are required to put it back in... aligning the filler tube back into the fuel door area is about the hardest part.
