Question about 2010 Ford F-350 Super Duty

1 Answer

Fuel backs up when fueling

I have a 2010 f-350 with a v-10 and a 40gal tank. Recently it started becoming difficult to get fuel into the tank as the filler neck would fill up and shut the fuel nozzle off. I have to keep at the nozzle at all times and it takes about a half hour to fill the tank now. Pulled the tank and made sure i could blow air through the two tank vents and the filler neck and vent tube. Everything looks ok so what else could be the problem? The anti syphon valve moves freely in the tank but could it be jamming somehow when the fuel hits it?

    already disassembled canister and looks ok. solenoid is open and all ports pass air freely. also put air to lines from tank to evap canister and air is felt from all connected tubes.

  • jason gagne Nov 05, 2012

    is it possible there is something wrong with the anti syphon valve or the purge valve?

  • jason gagne Nov 05, 2012

    looks ok

    If the anti syphon look ok and not damanged in anyway...I dont think that the problem. The purge valve does not do anything with tank venting when filling. I would double check all vent lines and filler neck....make sure there are no kinks in any lines and something as small as a spider web in one of the lines can cause a problem like this.

    Replaced the vapor canister and valve. Now the truck accepts fuel at full pump output with no issues. On a side note the canister wasn't plugged just dirty and it still caused this issue. Thanks for the help.

Check the evap fuel canister...make sure its not clogged with dirt or fuel. Check the evap canister vent solenoid- it should be open with the car off.

theres a problem with the pipe that goes from the gas tank to the gas cap.Look under neath and see if the hose is pinched or bent.Another cause could be who ever owned it before had the tank out and they messed up the hose when they put it back in but that is differently the problem..

SOURCE: Replacing fuel filler neck on 2000 Crown Vic

Good news, no the tank doesn't have to come down. However, there needs to be less than 3/4 tank. Jack it up and set on a jack stand, remove the wheel, four screws housing to pipe, filler pipe sensing hose from filler pipe, screw retaining the cap, four retaining screws from filler pipe, screw from filler pipe retainer, slide into the tank until it can be rotated and pulled out through the fender. lube the tank grommet with clean oil and reverse the removal for install.

SOURCE: 06 Mustang Gas Tank; Last 2 times I couldn't take

There is a fault with the fuel tanks in the 06 cars (and some 05). It is a well known problem and Ford has issued a service bulletin on the issue.

It also seems to be a problem with the fuel pumps at certain gas stations but not others. Try a couple of different service stations (not the same fuel brand) and see if you have the same shut off problem because some people have found that the pumps at some gas stations do not cause premature shut off when re-fueling their 06 Stangs.

I would contact the nearest Ford dealer service people and see if they will rectify the problem for you FOC even though the vehicle is now out of warranty. In some vehicles the fuel tanks were replaced to fix the problem but not in all apparently.

In the meantime you can try 2 means to resolve the problem that has worked for some (not at the same time).

1. Turn the fuel pump nozzle 45 - 90 degrees when re-fueling and do not run the pump full bore. Slow the fuel flow a little.

2. I would avoid this one and I do not recommend it but it has worked well for some people with your problem. Turn on the car's ignition (not the engine)before you fill the tank . Switch it off immediately you have completed re-fueling.

Try changing the fuel filter. If that does not help, have someone test the injector pump for pressure. Last would be a compression test on the cylinders. Drain oil and replace oil filter very soon.

What has happened is the diesel fuel is a lubricant and gasoline is a solvent. As gasoline is much thinner, it could wash down the cylinders and get into the oil pan thinning the oil and ruining the bearings. This would be the reason to test the pressure in the cylinders to find out if you lost compression with the rings in the cylinders.

Next, the injector pump for the diesel has seals and tolerances for inside components. Again, since gasoline is a solvent and not a lubricant, the internal parts could be worn out by not having diesel fuel to lubricate the injector pump parts.

If someone working at the fuel station made this mistake, all the costs should be paid by the station. This is something which could be taken to court if the station does not pay.

This problem is caused by a failed fuel pump outlet pressure check valve, it is part of the pump and not sold as a separate part. The defective check valve lets the fuel pressure bleed off and drain back to the fuel tank, when you go to start it the line must be filled and the injectors purged of air, this takes time and causes hard starting. The fuel pump is inside the fuel tank, the fuel tank must be removed to replace the pump and sending unit assembly

You may have a fuel tank vent valve that isn't working. This valve lets air into and out of the fuel tank as fuel is added to the tank and then later used by the engine. If the valve won't open or is plugged with dirt/dust/debris then it's becomes very difficult to add fuel to the tank. This problem would also cause the EVAP system to fail a self test and turn on the check engine lamp with a related service code. Often there is more than one reason a particular code like this can be set, a loose fuel cap being just one of them, and it takes a bit of testing to determine the exact cause. A good service facility should be able to test the system and determine what is wrong fairly easily on this one. Good luck, hope this helps.

2000 volvo s70 difficult to start, more so as fuel level drops. Cranks fine. Recently changed MAF sensor, B+ cable, plugs, fuel filter - no improvement.


Sounds like the fuel pump, as the levels of the fuel tank drop, there's less natural pressure on the fuel, which would definitely make it harder to start with a weak fuel stream from a bad pump.

How do you get to the fuel pump on this car is there a way without drop the tank? Also the pumps works but whinns and when i and tooling around town after it has been running for a while at low RPMs the...


The fuel pump is located inside the fuel tank. You must drop the tank to service it. You have options when you repair it. You can replace just the motor (cheaper) or you can replace the entire harness including the motor (expensve but easier).
It is difficult to determine which componant of the fuel process is bad. There are fuel fuses both in the fuse relay and in other areas such as under the hood. I don't know exactly where on the Monte Carlo.
The fuel pump powers up before you start the engine. To hear the fuel pump without the vehicle on, have someone "almost" start the car while you are underneath listening. Just before you start the car, the pump will turn on for about 3 seconds to pressure up before the car starts. Then it will shut off if you do not start it.
It should not be too difficult to drop the tank. Dissconnect the (-) batterey terminal. There should be some bands that clamp together with a long bolt that hold the tank up. Make sure you open the gas fill and disconnect it because that will also hold it up and keep it from dropping. There should also be a ground wire nearby that will need to be dissconnected. There will be several little clamps that hold the fuel lines connected to the frame that will need to be undone so as to create slack in order to drop the fuel tank.
If you have never done it before, you may need someone to show you how to remove the pump. There are rings with little tabs that need to be spun counter-clockwise. They might be covered in oil and dirt and difficult to see. Clean this area as much as you can. You do not want debris to fall in your tank when you remove the pump. Spinning the rings can be difficult. I use a screwdriver and a hammer and gently tap in the correct direction, alternating to a different tab every few taps so as not to shear off the tabs. Then replace with the correct part. Lifting the tank and getting the bands back in place is difficult but can be done.

My car doesn't start after putting gas in it


hmmm, is it a diesel or gas powered VW?

if gas, did you use E85 fuel? this will make it very difficult to start and run very poorly once runing. I would suggest a fuel sample be drawn. but first, call the suplying fuel station and ask them if any issues with their fuel. It is becoming more of a trend that teh 10% ethanol is "dropping out" of the fuel. this process is called "phase seperation". phase seperation occurs when water becomes mixed with gasoline that is mixed with ethanol. the enthanol is loosely bonded to the fuel itself, but is much more deireablke to mix with water than gas. so when your service statiojn refills their underground tanks, and the water content in bottom of tank is high, the water mizes with the fuel and pulls the ethanol out of it. the ethanol sits on bottom of storage tank, waiting to be pumped into your car by the submersed pumps in the bottom of tanks....so now that chemistry class is over..call your gas station, ask them if issues with fuel, if co..great! they will tell you what to do next..if not, draw a fuel sample and if it looks like ditch water with water down looking maple syrup like goo in it..that is phase seperation @ its finest.

hope this helps you

your 4 thumbs up is appreciated

Fuel filter is not fun on this car. Located in the front top of the tank beneath the car. Tank must be lowered to gain access. Banjo nuts difficult to access. Fuel under pressure in line will squirt out... messy. Good job to be done on a lift.

your fuel pump is in the fuel tank. and your fuel in the tank is what cools you pump . i have seen alot of fuel pump failure when people run very low on fuel.
when you turn on your keyswitch you should hear a hum of the pump . before replacement you should always check voltage to the pump. to make sure.
