Eric, I had the tank off your car a couple times. The pump is newish, but the sending unit is original.
If memory serves, removing the exhaust from the hangers, and unbolting the driveshaft gives you just enough room to unbolt the tank and let it "sit" on the exhaust. you're going blind, but you can reach up on top and get the basket out that way.
Of course that was with the stock exhaust, which I presume you've changed..
