It seems the Flashpoint of gasoline is lower than that of diesel, but the autoignition temperature is higher. The autoignition temperature of gas is 477°-536°f, and diesel is 410°f.
The flash point of gas is -40°f, and diesel is 126°f.
I'm not arguing with you. Just adding info.

Let me rephrase: I put together diesel pump, Davco fuel pro with clear plastic cover, some fuel lines and a fuel tank - no Diesel engine.
When I put diesel in the tank and start the pump no bubbles in the fuel filter. When I put gasoline in the tank - a lot of bubbles....
Now don't tell me about engine damage, because, there is no engine here)

Friend of mine accidentally put some gasoline in his 2004 Columbia. The tanks were almost empty, so in the tanks were mostly gasoline.
Mostly Gasoline. Almost Empty? Some? Is 300 gallons some?
Started the truck and after 5 minutes, the truck started misfiring and we saw big bubbles in the fuel filter screen. The engine shuts off.
5 minutes of running a engine with gasoline. tsk tsk tsk. Our Companies over the years have engines BLOWN up with gasoline instroduced.
What codes did that ECM throw up? Sure as hell puked a bunch of codes...
Fuel Filer Screen?
There should be two or three fuel filters next to the engine inside the steer tire space. So you pulled em all? Hopefully after you shut the engine off?
That gasoline with vapors is a bomb.
We open the fuel filter and immediately notice the smell of gasoline, tanks were drained and everything was cleaned.[/color=black]
Where in hell were you when you filled the #### fuel tanks with GASOLINE. Are you so dense as to fail and recognize various very important signs that is gasoline rather than Desiel fuel> -
You stated you started the truck, ran the engine for 5 minutes.
If you claim NO engine at all, then I MUST suspect you are trolling the bejesus out of us all.... A fuel pump or whatever does not a engine make. To run through your fuel FILTERS??? WTF?"
I am baited to posting again and again because I cannot resist this. I will stop here and leave it to the Mods and the community.Bean Jr. Thanks this. -
The gas was flashing off into a vapor as the pump drew it up from the tank. Diesel fuel doesn't vaporize as easily.
Verdel Thanks this. -

A lot of crazy people around here, they always answer something, you never asked them

We are too far apart. Gas turns into a vapor is a good idea. Viscosity is another.
Engine codes on a engine is specific to a engine, Usually the fuel filters are the casultiy of either running out of fuel, JELLING the fuel due to too cold, getting WATER into the fuel due to a bad pump seal like happned to me twice... and gasoline or other chemcials that DO NOT belong in the desiel period.
Those filters, however many or few they are depending on egine HAVE to be thrown away and new ones installed AFTER YOU CORRECT the fuel contamination issue by throwing away or properly disposing with a waste hazmat collection vehicle whatever was in those fuel tanks when you dirtied them up.
Again, to make blanket assumptions about me; whom you never met before this topic and your attitudes that refuse to accept learning, lessons and respectful ideas, teachings etc which in this case come back to screwing up by putting gasoline where it don'e belong makes for a impossible working relationship. Ignore lists is the first step to resolving this tension that is unecessary and drama which is unhelpful over time.
Im going to go ahead and close the converstation by brushing off the steering wheel insult attempt. When you have been on the road as long as I have and never put gasoline where it does not belong then you can tell me or anyone what you think of them then. Until then take it easy. No one is likely to help you or care to continue the problem of gasoline in a heavy truck. It's one of those commandments taught in school 40 years ago. You just don't do it.
Why?
The older 58 White and a couple of other tractors took Gasoline and had engine operation ratio in excess of 5000 rpm and a different behavior compared to the Desiels. There was also leaded gas which hopped things up compared to ordinary unleaded gas which was not so hot back then. You were careful what you put into the tank.
There was a company driver at Hahn Transport in New Market who had a R model mack, he stuck his gasoline hose into the nearly empty 60 gallon fuel tank at 3 am ready to for the new day. The next result was shortly after KABOOM. No more engine. And everything attached to same Blown up as well. Driver was fired. Then billed tens of thousands of dollars as for the rumor.
That is my history and what I know of never putting gasoline into a desiel tank for any reason whatsoever. You screwed up; I tried to help you and get insulted in return. Again we are too far apart. You will be put on ignore nicely so you do not have to deal with me anymore.
Maybe others will step up to help but again, you never put gas into desiel. Period.
