Well it sounds like the leak is at the right rear of the engine as you face it if so right back by the fire wall is where the fuel lines couple together if you take the lines apart there should be a o-ring on eack line check that out and see if that is where the leak is

Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Evaporative Emission (EVAP) canister or fuel tank leaks
- Evaporative Emission (EVAP) system hose leaking
- Fuel tank leaking
P0456 Chrysler Description The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage. During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

Instructions
  1. Raise the hood of the Kia Shortage view the interior. From front to back you will see the grill, the radiator, the radiator fans, and the engine. On the top of the engine is the valve cover---an aluminum cover that encloses the top of the engine---that is bolted in place.
  2. Look behind the valve cover for an aluminum rail that goes across the back of the engine. Inserted at equal distances---both below and into the rail---are tubular injectors that are also inserted into the engine. The aluminum rail is called the fuel rail. It is a hollow tube that holds the tops of the injectors and supplies them with fuel. Each of the injectors are also plugged into the engine wiring harness.
  3. Inspect the injectors for any signs of fuel leaks. Although rare, leaks do occur, especially due to age and mileage. If leaking, do not drive the car as there is an increased risk of fire. Repair the injector seals before driving the car again.

Removal & Installation

Exploded view of the fuel rail and injector mounting


Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.

I have a 2003 nissan altima and smell fule at ecslerashion


The smell of fuel at acceleration may be due to leaky fuel injector seals or other fuel system leak in the engine bay. Fuel leaks are nothing to play with. Have a certified mechanic examine your intake manifold and fuel rail for leaks, as a problem of this nature that is not repaired could lead to a vehicle fire and possibly death.

I have fuel leaking out fast behind the assembly for the fuel injectors. Where can i find an exploded view of this and what is the assembly called? Thanx for your time.


Get a rebuild kit for the throttle body. Be sure to get the rebuild kit for the fuel presure regulator. This is probably your leak. Most quality kits come with good instructions! Get new o-rings for fuel lines if they don't come with either kit.
