settle an argument

[DSteimle]

quick question, i work for a mopar dealer. recently a customer filled up his 99 r2500 with 28 gallons of gasoline. it shut off shortly afterwards. one of my diesel techs says he did lots of damage to engine and injector pump while myself and the other diesel tech says drain and clean and go. :-{} i dont think we can come to an agreement without outside intervention. any opinions on whose correct would be appreciated

Here is a link where we talked about the same thing a while back.

Gasoline

Bad Bad Bad. That said I can add that I put gas in my truck and ran it till it quit. Not quite the same circumstance. I only added about 7 to 9 gallons. In others words, toped it off. Noticed that the truck had quite a rattle, Drove about fifteen miles and when I stopped at a corner, the truck died. Drained everything and filled the tank with fuel.



My truck is manual and I used the chain drive starter to pull the truck and purge the pump without the high pressure of the injectors and killer load on the starter. That was 300k (three hundred thousand) miles ago. I did no damage apparently. You may not be that lucky.



Drain it and purge the pump with the injectors unhooked. If it runs, you lucked out.

Purge and get a new fuel filter

This has happened to my vehicles on several occasions. 1) Wifes MB 300SDL... . thanks to the gas station attendant; 2) One of my Salesguys driving one of my D250s ran it for approx 50 miles... duh; 3) My delivery drivers now understand that the correct fuel handle is green... . ran our Isuzu NPR until it stopped cold... still runs ok with 150K miles ..... drain the tank, change the filter, re-prime and you should be OK.

the correct fuel handle is green....

Green is NOT universal for Fuel. I run into places across the US and Canada that have the fuel as yellow, green and black with regard to the plastic cover on the handle. READ the pump designation and if you have doubt, smell the nozzle. Bad enough in your home town but worse than bad half way across the country. At a given location, gas and fuel will USUALLY be different but don't count on green as an identifier for fuel.



My incident with gas in the fuel tank was the result of a large sign directing one inside to pay after dark that covered the GAS markings on the pump. I was at an island that I THOUGHT was fuel only. I lucked out but I never fill without thinking about that time. The sign was a violation of law as to clear markings. I still had to deal with the problem.

The VP pumps in the newer trucks are extremely sensitive to fuel issues, including the WRONG type fuel.

It is highly unlikely that this truck did not suffer damage from this event.

Remember, the VP's have failed due to a modest loss of fuel pressure/volume during normal operation, usually caused by a bad lift pump for example.

If the system was charged with gasoline and run on that fuel internal VP damage is pretty much a forgone conclusion. All that remains is how long the pump will continue to run before failing.

Look for rough/poor idle, mileage drop, power complaints, excess smoke, hard starting as examples.

I also wonder about valve/injector damage as well.



Hate to say it, but my opinion is. . get ready to replace the pump sooner or later.

Even though the color of the pump handle may vary, I got the green fuel cap from Genos. Several times it has caused me to "think" before I started fueling. After driving for 15 or 16 hours, my brain shuts down a couple of cylinders..... of course, it does that when I wake up too!!



There was also an article several issues back that discussed accidental fillups.

I haven't had this with my truck yet, but did have it recently with my John Deere diesel tractor. My brother-in-law accidently filled it with gasoline, and then never told me about it. I spent over a week trying to figure out why the tractor began running rough and going into runaway mode during shutoff. Finally I drained the tank and fuel system and refilled with fresh #2 - problems disappeared. Unfortunately, I had about 2-hours of total run time on it before the solution was discovered, but hopefully no damage has occured to the pump or injectors. So far it is still running great!
