Question about 2003 Hyundai Accent

1 Answer

Fuel leaking from top of tank

I have a 2003 Hyundai Accent and i have a fuel leak at the top of the tank where the sending unit fits into the tank. It only leaks when i fill it up and the leak appears to be at the seal between the sending unit and the tank.

I have changed out that seal once with a new one from Hyundai and it still leaks.

Any other suggestions?

i don't have a problem applying some kind of sealer at the rubber gasket seal but wonder what kind of sealer would work in that condition?

    No check engine light - that surprizes me. i know the fuel IS leaking at the seal where the fuel pump and sending unit (combined) fit into the top of the tank.

    Thanks for asking more.

    Do you have a 'CHECK ENGINE' light? If so, is the code an EVAP system leak?

Ok... you can go to and register your veh (VIN). Afterward, you'll have access to manuals, serviced bulletins and wiring diagrams.

Where is the drain plug for the hyundai accent 2003 petrol tank

There isn't one. The unit comes in two halves but you can't get in easily. it's a bit like a box within a box with seels. pull out the main feed to the engine or cut the pipe half way down and re-seel. the new plummers stop leak works a treat.

The 2000 model year Accent adopts a different "pressurized" leak check system capable of detecting a 0.020" (0.5 mm) diameter leak (previous Hyundai systems detect a 0.040" [1mm] diameter leak using engine vacuum). The new system uses a Diagnostic Module for Tank Leakage (DM-TL) to close and pressurize the fuel evaporative emissions system. The DM-TL replaces the fuel tank pressure sensor and the canister close valve from previous systems. Other significant changes were made to the system logic, including several new diagnostic trouble codes. It compares the differences between the 2000 model year Accent and previous evaporative emission systems... Que puede ser? Tiene dos opciones. Primero, puede pagar que un tecnico diaga el problema (exactamente) o sigue, secudariamente, su adivnaza.

Hyundai accent is 2009 model. On a really hot day the car smells badly of petrol. Smell mainly in the back seats. Especially strong in the trunk (dicky). Took it to two different dealers. Here are same...

Coolant smells like fuel, i think you need to find a new mechanic, obviously there is a problem around the fuel tank, does it do it all the time, what about when tank is half??? I would be checking the fuel tank breather, fill fuel right up to the top, go on a bumpy road or just do a sharp left and right (safe speed) and have a look underneath where the tank is to see if there are any wet patches, if there is a leak then you have found the problem, just need to find where the leak is. If there is no leak than i would deffinately have the breather checked out, one other thing to check would be your fuel filler cap, either way this problem should not be there and be fixed by Hyundai, it is a serious health problem!!!

I have hyundai accent 2003. While driving the engine died. Checked fuses,ignition,fuel pump(don't know if the pressure is right),starter is starting ok.

#1. Scan for trouble codes. If any, record them and let us know which ones they are.
#2. Connect a fuel gauge to the fuel delivery line at the engine... try to start the engine while monitoring fuel pressure... if there is fuel pressure (approx 35 to 50 lbs), the problem is elsewhere.
If no fuel pressure, check fuel pump relay, fuse, wiring to fuel pump connector (power & ground - use 12volt test light). If power & ground are present, problem is the pump (fuel filter is attached to the fuel pump inside the tank).
#3. Check injectors for injector pulse, check ignition coils for spark to spark plugs.

This DTC (P0442) depends on what caused the code to set. Most times it's simply a loose fuel cap or the O-ring on the fuel cap is damaged OR dirt got between the O-ring and the mating surface of the fuel filler tube. There are numerous possible causes for the DTC you have -- Fuel cap, pin hole in fuel system (evap hoses, fuel tank, fuel cap), canister close valve leaking, fuel tank pressure sensor malfunction, purge control solenoid valve malfunction, etc.
BEST SOLUTION: Take the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). If you perfer to try and fix it yourself, Go to and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

Replaced fuel filter on 2000 Hyundai Accent, now the car dies more often.

I would make sure the Arrow on the fuel filter is going in the right direction. The arrow on the fuel filter should be going towards the engine away from the fuel tank,

If you are sure the fuel filter is on correctly. Check for leaks,

The next step would be to change out the fuel pump. The pump could be on it way out.
Low pressure or intermittently no pressure .
