Question about 2002 Suzuki GZ 250 Marauder

1 Answer

My son just called to say he put diesel in the tank. He hasn't started it yet. Is there a drain on the fuel tank or does he have to siphon and then use rags to soak up the rest?

Hi and welcome to FixYa,

Initially, what could be suggested are:

  • remove the fuel hose end connected to the carb;
  • fit that freed end to a suitable container;
  • depending on the version, PRI setting of the fuel valve/control would make the fuel in the tank to flow;
  • if PRI is not available, the smaller hose leading to the carb/rubber coupling from the valve would have to have a vacuum to enable fuel flow;
  • alternately, the entire tank could be removed and inverted to remove the fuel inside;
  • there are drain screws at the very bottom of each carb to remove the fuel inside the bowl;
  • flushing the tank with gasoline would help after diesel removal;
  • if diesel was removed and replaced with appropriate gasoline, it is possible bike may run a little rough for a bit of time;
  • your suggestion of siphon will work, no need for the rag (though not a bad idea).
Good luck and Thank you for using FixYa. Happy Holidays.

3:1 gas/ diesel in 2011 kia what can I do to remove it?

This site may have all your answers:

Basically do NOT drive the car and have the gas tank drained or talk to a mechanic.

Accidentally putting diesel in a gas car If you know that you have accidentally put the wrong fuel in the car, then don't compound the mistake by driving the vehicle while trying to think about what to do. Instead, call your mechanic immediately. At this point, the damage isn't permanent. If you drive and continue to drive, at one point the vehicle will stop and you will still have to have it towed.

There are two things you can do to try to fix the damage:
1. Try to clean up the damage yourself - have the vehicle towed home if it's not there already, and get as much of the diesel fuel out. How? By siphon if you can or any other method that you have available. Once you have as much of the diesel out as you can, fill the tank with the correct unleaded fuel that you normally use. Try to start the vehicle. It could take several attempts but it will start and it will smoke - a lot. It will continue to smoke until the last dregs of the diesel make its way through the system. It might run a little rough until everything is cleaned out. How it runs will depend on the proportion of diesel fuel relative to gas left in the tank.

2. Alternatively, have your vehicle towed to where your mechanic is and have the fuel tank drained of all the diesel fuel by a profession. They are also likely to flush out the whole fuel system. If the diesel stays in there for too long (and who knows how long is too long for your particular vehicle), it could ruin the fuel pump, lines and injectors. It is also possible that the diesel could have gummed up the spark plugs and filters. If this is the case, they will probably need to be replaced. Getting a professional to do the job will cost you anywhere from $100 to $500 and possibly a little higher depending on the extent of the damage.

It turned out my son put a diesel gas according to the technician. Around how much is the cost do you think?

well you need to drain all diesel fuel, install a new fuel pump and filter, clean injectors, get it running and go from there, fix any code the comes on, one think.... fuel tank or fuel cell called also a bladder may need to be replace if collapsed due to diesel caracteristics, the longer you wait the more damage, hope you did not drain EV battery down to zero charge, it takes an special charger only available at your dealer by request to Toyota head quarters

What would make my truck misfire if my son put deisle in it

You're joking, right? First question... Why would your truck misfire if you put water, Jello or peanut butter in your gas tank? Answer: Because your truck wasn't designed or set up, to run properly on any of those as a fuel source! Second question... Is you 2005 Trailblazer designed or set up to run on diesel? If your answer is no, slap your son in the head, drain your fuel tank and flush all the diesel from the system. Replace it with the unleaded fuel it was designed to operate on and educate your son on fueling up your truck. Your truck should stop misfiring once all the diesel is gone. Good luck!

I accidently put diesel in my John Deere riding lawn mower. How do I safely drain the tank. Or do I need to take the tank completely off? If so I need directions.

If you did not try to start it, you will need to siphon, pump or **** out the fuel tank. The last J.D. that I emptied the tank in I used a turkey baster to draw out the bad fuel. I guess you use what you got. Hopefully your fuel is pumped to the engine and the fuel line goes into the tank from the top. If so all you have to do is empty and replace with gas. If the fuel line drains the tank from the bottom and/or you tried to start it with diesel in it you will need to (after emptying the tank) remove the fuel line from the carb. and direct it to a container, remove the bowl nut of the carb. to drain carb. be ready to clean up a little spilt fuel catch if you can or have rags under and ready. Turn the ignition key for engine to turn over to operate the fuel pump and clear the line. Put a little gas in tank and flush fuel line by using fuel pump to clear. Change fuel filter and put everything back together. Remove and clean/replace spark plug. Test it. Inspect spark plug again if necessary.

Escort 55 D, wrong fuel in tank ,is there a drain plug or can I syphon the fuel out

Hello, If the D is for diesel, then you will have to siphon to fuel out of the tank until you make the fuel tank light enough to drop the tank. Then remove the tank, turn it upside down after removing the fuel pump. The gasoline that is in the tank by mistake at best could be used in a 2 cycle engine. For the most part it is junk fuel. Otherwise it can be used to start fires or clean tools.

Add a small amount of diesel to the tank and swish it around and dump that fuel as waste. Then try to immerse the fuelpump(if in tank) in diesel fuel to get out the lighter more explosive gasoline. Try blowing out the fuel that has reached the motor and have the fuel filters changed. When everything is together add only several gallons to prime the system before trying to start it.

If you suspect gasoline is in the injectors, they may have to be removed and cleaned too.

Now if you added Diesel to a car using gasoline, then it can be a little easier to fix. You can use the fuel pump in the tank to drain the tank via the fuel line coupler at the fuel filter. Remove the filter and turn on the key with a rubber line connected to the tank side of the fuel line. The fuel pump will drain the tank. It would be good to remove and clean the tank, but not necessary. The residual Diesel fuel will dilute over time.

If either fuel is mixed together there will be vapors. Ventilate and put down a rubber mat or blanket under the catch bucket to insulate it from sparks and static.

I hope my solution is very helpful to you. I want to add that sometimes Comprehensive car insurance may pay for this service. You should call your Insurance company and see if your insurance covers this.

I accidentaly put diesel fuel into my 2000 Acura 3.5 RL, the tank is 18 gallons, it was at about 2 gallons when I filled the tank with 4 gallons of diesel, I got the car towed back to my house, what steps,...

Very easy! Get a siphon and get all of the fuel out through the fill hole. Then put 5-10 gallons of good fuel with a can of Seafoam this will help to dilute any remaining diesel that is left. Start and let idle for at least 10 minutes. It may run rough for a little bit but will clear up and you will be ok! Good Luck!

Volvo 2003 marine diesel problem starting

It sounds like you need to vent the pipe before the fuel lift pump so the vent is open when the pump is off. That way the fuel can not siphon to the lower tank. Then you would need a valve in sync with the lift pump to close the vent so the pump can draw. Perhaps there is a lift pump with that feature built-in.
