My 2005 rx8 is leaking fuel I removed the back seat and gas was there . do I need to replace fuel pump or maybe the hose?

google youtube and find out if there is a video pertaining to changing your fuel pump..U might be able to access it from under the back seat or from in the trunk...there for u wont have to drop the tank..sounds like a bad fuel hose from tank to fuel filter via Engine

You might need new spark plgs and/or wires. Or a new fuel filter

There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.
