Make sure it is coming from pump and not fuel line.. The Fuel Pump carries a large O Ring either it's dry rot damaged or off track. Drop the fuel tank unscrew the cap fix o ring properly .

GM had a fuel pump module problem back in those years where the plastic broke , where the delivery hose hooked up to . This caused a substantial leak ,you can't really see the broke part till you drop the tank . I don't know if this was a problem on Malibu's ,I saw this on cobalt's . There was a Factory recall on some ! With a TSB - technical service bulletin ! I'd have a second opinion , call the dealer also .
We've had similar problems with our Aztek and Buick.
The problem was with the Body Control Module and was beyond my fixit skills.
The local GM dealer attended to it for a cost of approx $1,000 per vehicle.
Definite PITA
Hope you have better luck.
The fuel "level" sending unit is located on the side of the fuel pump module, see red arrow on picture below. The fuel tank will need to be dropped and the fuel pump module removed in order to replace the fuel level sending unit. You can expect to pay a couple hours of labor to remove the tank and replace the level sending unit.
the fuel tank pressure sensor is located on top of the fuel pump module. The fuel tank will still need to be lowered to get at it but the fuel pump module does not need to be removed from the tank to replaced it.
i just bought a 2005 malibu maxx from a dealership. It was having a popping sound when i would turn the wheel back and forth. Had the dealership fix it. THEY said they replaced the ( rack and pinion ) for the steering on the car. Don't think there is a recall on that. GM had a lot of problems with that popping noise on their malibu maxx. Hope that might help.
From the sound of it you have a fuel leak somewhere. I have seen this to be the fuel pressure regulator under the hood on the fuel rail that leaks. If not, then you will have to locate the cause of the leak and have it repaired.
TAKE VECHICLE TO AUTO ZONE OR ADVANCE AUTO PARTS THEY WILL CODE SCAN YOUR VECHICLE FREE.SERVICE ENGINE SOON LIGHT COMING ON COULD MEAN EVAPORATIVE LEAK OR CYLINDER MISFIRE.BUT AUTO ZONE WILL SCAN IT AND TELL YOU WHAT TROUBLE CODE YOU ARE GETTING.
The fuel filter is located in the fuel tank and is only serviced when the fuel pump is replaced, don't know why GM did this but never the less that is the fact of the matter.
