Try above the fuel tank. Which might be under the back seat? Turn the key to the run(on) position with the engine off and listen for a hum near the gas tank that means that it is pumping I think? Goodluck!!
The pump inside the fuel tank. To check remove the gas tank cap and put your ear to the opening,have someone turn the key to on(not start) and listen for a humming noise as the pump will run for a few seconds.
