if you just want to inspect it, you can do that under the rear seat, should just be able to get to the sending unit with the sock filter on it
should you need it dropped all the way, the subframe has to come down as it cradles the tank and it's about a 2hr job if you have a lift and tools and you don't stop for tea and biscuits.
if you have doubts that any of the ten suspension arms will come off your hubs/you don't want to fork out for stabilizer end links, I strongly recommend undoing the abs sensor plugs and taking the calipers off the carriers, then you undo the struts from the hub or the top hats from the parcel shelf and the 4 bolts holding the subframe in and just drop the lot down
