You are watching: How to drain fuel tank on ford f250


We have a 2012 F-250 Power Stroke at work that someone just filled with gasoline. It hasn"t been started yet. What"s the best way to drain the tank?Can I unhook a fuel line and use the lift pump to pump it out? (I assume there is an electric lift pump in the tank?) Or can I can it all out the DFCM somehow?PS - Tried the search feature and couldn"t find a tank draining procedure.

A shop usually drops the tank, pumps the gas out and then flushes the tank. The fuel pump does not draw from the very bottom of the tank. Unless you turn the tank upside down to drain it, you are still going to have some gas in there.

Yea, dropping the tank is fine, but I"d sure like to get the fuel out first. That"s easily 200+ pounds.

While it would probably take forever. Just opening the drain valve on the fuel filter will allow the fuel to drain out. I don"t know what I"d catch 37 gallons in . But at least I could leave it to drain and go work on something else. When the majority of the fuel was out, the weight would be lighter so you could possibly man handle the tank.

When I made this mistake at gas station years ago with my 7.3 PSD, I got a buddy to push me away from the pump. I went and got a pump and pumped the tank out into a 30 gallon drum we had at our shop. I then dropped the tank and finished draining it. Next I flushed it with 5 gallons of diesel and drained it again. I changed filters; no gas had gotten to them. I put five gallons in the tank, started the truck and backed it up to the pump. I used the right nozzle this time.

I don"t see what dropping the fuel tank accomplishes over sticking a tube in and pumping it out. I would change all of the fuel filters, and refill the tank with fuel.Then I would go through the key on/key off 6 times or whatever, and maybe toss both fuel filters again before starting up, just to clean the lines.

You need a lift and a transmission jack. You won"t get it all out unless you pull it and turn it upside down. Dealers charge around $200-$300.
Unhook your fuel line and use the stock pump get as much out that way as you can. I can"t say if gas will hurt the new motors but a little is a good cleaner in every other motor I"ve worked on from the 6.9"s on up to big tractors and heavy equipment. If you are worried about it add diesel to the tank and keep pumping it out. I would run the truck a few days before changing the filter though. Like I said gas will clean up a diesel so there is going to be stuff breaking loose.
Gas is a dry fuel and does not contain enough lubrication to lubricate the HPFP. It can cause the HPFP to fail and result in a $12,000 repair bill. Do not assume it will not damage your engine.

Wrong Wrong Wrong on anything 2008 and up that uses High pressure common rail fuel injection.The HPFP is lubricated by fuel and gas, just like water will dry that up and then send metal all through the fuel system cauing massive repair bill not covered by any warranty.

Like I said, the dealer will do it for around $200-$300. Or spend about $9000 replacing the fuel system if you do it wrong. Even diesel fuel with a small amount of gas in it will lose some lubrication properties. In these fuel systems I wouldn"t take that chance. If you can"t do it yourself pay someone to do it right.
Pulled a dumbass move and filled tank with regular. Check on various sites like this and conversations and ford bulletin made it sound like I should pull the tires off and throw the truck away.One suggestion said to drain some fuel from the fuel filter value. I did that but thought it was slow, so I got a rag stuffed it in the fillertube then pressurised the tank with a compressor. Took about 45 mins but I got over 80 litres out(tank holds 85), then jumped on the back bumper, got a little more to go in the fuel sump. Poured 4 litres of fresh diesel into tank, jumped on bumper with air pressure in tank to force the rest out.Put conditioner in the tank with 20 litres of fuel. It took 6 or 7 turns of the key, it started, runs smooth and has been good ever since.Probably not the recommended procedure but it work for me.Kirkl
