I accidentally put desil in my gas tank. I ordered a siphon and siphon won't work on the tank I put the desil in. I have two tanks. I tried it on my second tank witch Is the back tank. And it worked

you can take the fuel rail off and run the pump and catch the fuel..

If that tank has a drain in the bottom, you can undo it and let it drain. ONLY problem is having enough cans to put the drained gas into as it comes out! Diesel is not as dangerous as gasoline but you MUST still use every precaution while doing this. You don't say how many gallons you have put in the tank but you will probably need to be able to start and stop the flow from the drain by putting the drain plug in and out.

also how much diesel did you put in?? how much gas was in there before.. we use to add some diesel to lube the upper cylinders some years ago... i (me) bought my new z06..took it to the gas station started putting in what i thought was prem..we have some gas stations here where you can still get 100 oct.. and about after 4 gallons i noticed it was diesel..so i freaked and thought ok ill fill the rest up with the 100 unleaded.,,anyway it smoked pretty bad for a few min then it cleared up...it never did any harm to anything emission related,,,anyway oldtimer said the look for a plug..my ford had one but where it was at i would have still had to pull the tank out.. ace hardware has all sorts of hoses,dont know why you cant feed one down into the tank..by now you probably have it fixed.
