OK, it's my first post here, and I know you guys are goiing to have a real party with this one. I pulled my 99 Chev Suburban (diesel) into the Citgo Station and pumped 20 gallons of 87 octane gasoline into the fuel tank. I realized what I had done just as I replaced the fuel cap and drove the vehicle only about 50' into a parking spot. The obvious question is what do I need to do? If I need to drain the fuel tank, what is the easiest and best way to do that? Thanks for any help you can provide. :neutral:

Ahh, people do it every day. I have a company van that is diesel and I wait for the day I do it. I'm not sure what to do, I don't know diesels. On a gas engine, you can hook a hose up to the fuel rail and just let the fuel pump run. Only thing I have heard, is if a diesel runs out of fuel, it has to be primmed some how, so that may become a problem. I am sure a diesel guy will reply soon enough.

Simply siphon off the gas. places like walmart etc sell hand pumps that will do just fine. And then add diesel into the tank. There is no need to prime the 6.5L since it will simply push any air thru the system.

Mike: Thanks for the info - do you know if there is an anti-siphon device in the tank that will prevent me from getting a siphon hose all the way in?

Do it ASAP as if you put gas with ethanol in it will react with the diesel. It tends to turn to a bit like jello. A small amount won't hurt, but 20 gal in a tank that size will cause problems. Bad memory from one of the guys I use to haul gas with. 3500 gal. of 87 octane with 10% eth. into 6500 gal. of diesel at a station. Just glad it wasn't me that time. LOL

OK - here is the rest, and I hope the end of the story. I went to Auto Zone and purchased an $11.00 siphon pump and six 5 gallon fuel containers @$13.00 each). The hose for the siphon pump went into the fuel tank fairly easy after pushing by what felt like an anti-siphon ball valve. I pumped out about 15 gallons of fuel and then the siphon stopped because the hose was too short to reach the bottom of the tank. I went to Lowes and bought 10' of tubing and finished pumping out all the fuel in the tank (about 27 gallons - it took about 30 minutes with the siphon pump). Filled the tank with 43 gallons of fresh diesel (it's only a 40 gallon tank - WTF!!) and drove the truck for the rest of the day. The engine never missed a beat. Now I'm looking for a business that disposes of contaminated fuel - wonder what that will cost!! :happy:

Thanks to everyone who offered advice - it was much appreciated.

I'm in Norfolk, VA and afraid I would be arrested if I tried to dispose of it other than by lawful means. I don't have much success when I try doing things the easy way!! LOL

Most of them wont take gas.. And sadly im not in your area id take it and run it in the tractor.
Did you ever find a place to take the gas?? kinda wondering since when you have stuff like that and you want to get rid of it, its nice to know where to go.

When I worked at Honda, we had a couple cars that came in and the owner filled their tanks up with Diesel.. but they ended up driving it for a while and the motor would eventually quit running and they would realize what they did and tow it in.. We usually had to replace the fuel pump and injectors because they would be gummed up with this "jello" like substance.. and the stuff in the tank was pretty difficult to get out.
But, there were others where there were only a couple gallons of diesel in it and we just had to drain the tank.. I think in your case since there's more gas than diesel (depending on how empty the tank was.. I'm sure it only had a couple gallons of diesel in it to begin with?) that you'd just have to drain the tank and put some diesel in it..

Maybe just put an add on Craigslist explaining your situation; someone will come take the contaminated gas and run it in and old tractor or something.

The dump in our county takes what they call hazards waste (gas, paint, oil etc) on two days of the week. I live in Idaho so maybe we are just northwestern rednecks but I would give your solid waste disposal facility (fancy name for dump) a call to see.
