I dropped my tank to install a walbro 255. I unscrewed the four bolts from underneath and the four bolts from the outside. But even doing this you can't remove the tank totally cuz the filler neck won't fit through the hole. So how can you remove the neck from the tank?
i just left it in and spun the tank out from under the car enough to drop the new pump in....you don't have to pull the whole thing out it isn't any harder. just sit on the ground and get to work.
