You could, but Ill warn you. On mine, the lock ring was so rusted to the top of the pump, it took about 40 minutes just to get it to release.... with a damn air hammer. Not to mention, the lines coming off the pump, broke off into the plastic intermediate lines that are on the tank, so it took a long ass time to get those broken ends out without damaging the plastic lines (so there wouldn't be any further leaks). Also had one of the cage nuts spin loose getting the straps off, so that had to get cut and replaced too. Once you get the pump out, its easy. There's a little bit of work to get the tank down, and everything detached from it. 2 lines up front, the filler neck tube, you have to move the evap canister out of the way, and i think 2 or 3 lines at the back of the tank.
If you do it on the ground, jack up the rear of the vehicle and leave it high. Make sure there's not much fuel left in the tank too, as little as possible, so its as light as possible. If you end up doing it, TXT me if you have issues. I still have your #.
