The filter sits above the two fuel pumps. You might find it necessary to pull the main feed line (from the tank) to gain space to remove the filter element. If you find you cannot get the old filter out without pulling the main feed, you will have to have a plug readily available. I use a large bolt, which I stab into the line quickly. Even working fast, there is a fair amount of fuel that will gush out. Oh well, it happens. Just let the fuel dry before swapping the filters, and expect another spill when trying to reconnect the main feed.
