If you have replaced the fuel filter and fuel pump, but still smell fuel, there may be another issue causing the fuel odor. Here are a few possibilities:
Leaking fuel injectors: Fuel injectors can develop leaks over time, which can result in a fuel odor inside the car.
Fuel tank leak: If the fuel tank is damaged or has a leak, fuel can escape and cause an odor.
Fuel line leak: A leak in the fuel line can result in fuel escaping and causing an odor.
Evaporative emission control system (EVAP) leak: The EVAP system is responsible for controlling fuel vapors and preventing them from escaping into the atmosphere. If the EVAP system has a leak, fuel vapors can escape and cause an odor.
If fuel smell is coming from gas cap area, its most likely the gas cap that needs to be replaced or EVAP canister located under the rear bumper (below trunk) in black rectangle box. If its coming from the front of the car under the hood, check your PCV valve (brown PCV - passenger side near oil fill). If not PVC valve its most likely your fuel injector O rings are bad and need to be replaced, you need two O rings per fuel injector x16 total. https://www.youtube.com/watch?v=-iwIDs…
