THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 14-003-01, DATED MAY 18, 2001. THE REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE ADDITIONAL MODEL YEARS AND PARTS REQUIRED.
SUBJECT:
Fuel Tank Slow To Fill
OVERVIEW:
This bulletin involves correcting any or all of the following items as necessary:
^ Kinked/plugged fuel tank vent lines
^ Replacing the fuel tank control valve
^ Replacing the Leak Detection Pump (LDP) filter
^ Unplugging or replacing the fuel tank fill tube assembly
MODELS:
2000 - **2004** (LH) LHS/300M/Concorde/Intrepid
SYMPTOM/CONDITION:
The fuel tank is slow to fill because of lack of venting.
PARTS REQUIRED:
EQUIPMENT REQUIRED:
DIAGNOSIS/REPAIR PROCEDURE:
1. Disconnect and isolate the negative battery cable.
2. Use the appropriate service manual procedures to lower the fuel tank from the underside of the vehicle.
3. Inspect the vent lines between the fuel tank and evaporative canister for a possible kinked or plugged condition. Correct as necessary.
4. Inspect the LDP filter for being plugged. The LDP filter may become plugged by aftermarket undercoating or other debris. If the filter is found to be plugged, replace it with p/n 04581236.
5. Disconnect the hoses from the fuel control valve.
6. Use a hammer and brass drift to remove the fuel control valve lock ring.
7. Remove the fuel control valve from the fuel tank and determine the mold cavity number, refer to (Fig. 2). If the mold cavity number is 4, replace the control valve with p/n 05016387M.
NOTE:
IF THE VALVE WAS STUCK CLOSED, THE SYSTEM WOULD BE UNABLE TO VENT CAUSING A SLOW FILL CONDITION. IF THE VALVE WAS STUCK OPEN, THE VEHICLE COULD BE "OVERFILLED" CAUSING LIQUID FUEL CARRY OVER INTO THE CANISTER.
8. Some vehicles may have a fuel filler tube recirculation line that is plugged or restricted with paint from the filler tube supplier's manufacturing process. Remove the fuel filler tube.
9. To check for this condition insert a small ball bearing (1/4 in.) at the fuel tank end of the fuel filler tube recirculation line. If the line isn't blocked the ball bearing will travel freely through the recirculation line and out into the larger tube. If plugged or restricted, replace the fuel filler tube assembly, p/n 0458319AB.
10. Install the fuel tank and replace the fuel that was drained.
11. Connect the battery and set the clock to the correct time.
