Piece of cake. This thread has some good advice, but it's really pretty straightforward. That's a good writeup BTW...

You definitely want a new sending unit with a new collection tube filter while you've already got the tank out. The new sending unit won't necessarily correct the gauge issue. HOWEVER, do not hook up current to the sending unit without hooking up the Ground wire first! You will cook your sending unit and that will just suck. The gauge issue is another thread for another day, right?

Best advice one could really offer here is get that thing as close to empty as possible before attempting to remove it and use a jack so it can be lowered a little bit at a time, some of those hoses will hang up and you can't get to them immediately. Otherwise, just put it back the way ya found it, ya know?

i dropped my fuel tank about a month ago. it is very easy, the only part that was remotely hard was reconnecting the hose to the filler neck. and definately change out your sending unit. now the gauge issue. my gauge on my spedo never worked either. the guy that had it before me put a new gauge in it. but he didnt know what he was doing. all you need is a gauge that has 3 prongs on the back. one should be for positive, the other for ground, and the third for the wire that comes from the sending unit. if you want to check to see if your original gauge works though there is a really easy way. connect the positive to a 12v source and connect both the ground and the sending unit wire to ground. when you do this the gauge should move towards full. if that happens then the gauge still works.
if you have anymore questions just pm me.
