Fuel leak. Mechanic said it's the housing unit?

I took my car into the shop on Friday due to having a fuel smell. They said it is the housing unit that the fuel pump is on. When they called the dealership, they said the fuel pump has to be replaced, not just the housing unit and that my car has more than one pump. Is that possible? My car is a 2001 Honda Civic.

That it a fuel pump module (it consists of fuel pump and fuel pump bracket) "Some cars this is the only way you can get either one. Yours you can get either fuel pump or the module but you can't get the bracket without the fuel pump. Your module is plastic (not the fuel pump) and you can remove the 3 screws in the trunk under the liner should be able to see the fuel tank where the module is located. So either there's a bad o-ring or tank. If my memory serves me correctly the lines under your car are metal (I can't remember if they are plastic or metal over the tank) but I remember replacing a lot of metal over the corner of the civics back in the day
