Yes, just done mine, new senders should come with new seals, otherwise it's typically 5 bolts and a couple of wires to connect....
Just need to make sure the new sender is (a) the right flange fitting, there's a quite common standard ("SAE"?) 5 -hole one where the spacing isn't quite equal, (b) the right resistance, some (US-based?) ones are 30 ohm full 240 ohm empty, others are I think 180 full 10 empty (so work the other way round!) and (c) the right length for the depth of the tank
