99 Taurus Slow Fuel Fill

Greetings,
99 Taurus, base engine, purchased used-so no history on the problem. When fueling, it sometimes takes a very long time. The nozzle shuts off continually. It seems to go a little better if the flow rate is slower. I had a dealer look at it and they said it could require removing the tank and costing about 800 dollars. Any help would be appreciated. Thank You. Randy

There should a vent hose on the charcoal cannister. Make sure it is not blocked. Barring that it might be a valve in the cannister which would require cannister replacement

Also, if someone has changed the gas tank before they might have pinched the vent tube while reinstalling the tank.

Just a thought!!

Both posters are correct. Also, check alldata.com for any bulletins on this problem.

My coworker's 1988 Caprice Wagon has this problem. Depending on the station, the fill nozzle style and the way we pull in is how bad the problem is. It just might be an anomaly with this model due to the tank design.

Slow filling problem: a possible solution

Try putting the gas nozzle in at different angles. I have a 1990 Dodge Dakots pickup and depending on the gas station I go to the fuel filling rate can vary depending on the angle of the nozzle going into the tank.

ISSUE
The following may be fuel gauge/tank concerns:

1. Slow fuel fill at or ABOVE 3/4 of a tank/fuel fill nozzle clicks off. The fueling station's fill nozzle is incompatible with the vehicles On-board Refueling Vapor Recovery System (ORVR system) or has a higher than normal fill rate.

2. Slow fuel fill BELOW 3/4 of a tank/continuous fill nozzle clicks off. Blocked/crushed evaporative emission lines or blockage in the fuel filler neck or an ORVR incompatible fuel fill nozzle.

3. The low fuel light illuminates with 11-22 L (3-6 gallons) of fuel remaining and/or the customer can only add 38-45 L (10-12 gallons) of fuel. The low fuel light will illuminate on level surfaces with approximately 11 L (3 gallons) of fuel and 15-22 L (4-6 gallons) when on hills or during/after extended turns.

4. Fuel gauge does not update after fuel fill. The fuel gauge will not update for several minutes after filling if the vehicle is running or the ignition switch is left in the Run position. This is due to a normal anti-fluctuation slosh module time delay strategy.

5. The fuel gauge needle drops off full shortly after fill-up. The fuel level sender and gauge are calibrated to accurately represent a COMPLETELY FULL indication. Driving approximately 48 km (30 miles) will start to move the fuel gauge needle off of full.

6. The fuel gauge fluctuates at or below 1/4 tank. The fuel gauge fluctuation is due to normal operation of the slosh module time delay strategy. This prevents excessive fuel gauge needle movement.

ACTION
Verify customer concern(s) and discuss or perform the following for the 6 listed concerns.

SERVICE TIPS

1. Use the following 3-click fill method: Fill fuel at the fastest fill rate until first click. Allow approximately 5 seconds and continue to fill at the slowest rate until second click. Then pull fuel nozzle back approximately 25 mm (1") and fill at the slowest rate until third click. This fill method should provide a complete fill. Recommend that customer try a different fill station and use this method.

2. Inspect the three (3) evaporative emission vent hoses that are attached to the carbon canister for blockage/kinks. Check filler pipe for blockage. Inspect evaporative emission hoses between the fuel tank and floor pan for crush/kinks/blockage (this inspection can be performed by lowering the fuel tank).

3. Normal system operation. Review the customer's drive pattern that triggered the low fuel light and compare with the normal operation.

4. The ignition must be in the Off position during fuel fill (as stated in the Owner's Manual). This allows instant calibration between the fuel level and fuel gauge.

5. Normal system operation.
