Welcome to the forum. My info says, under the vehicle, driver side, attached to frame. Looks like quick connect fittings, you may a tool to release fittings, the autostores should sell the tool. Make sure there is no pressure on the system, before taking anything loose. Gas may run out of lines, don't let anything electrical be too close. If too much gas runs out, plug the line, till your ready with new filter. The picture is from autozone.
