I would explore removing the fuel pump relay and jumping the contacts. It will save time. More importantly it will save wear and tear on your ignition switch assembly. That is a mechanical device. Most all mechanical devices have some limited number of operations before wear becomes a problem.

An alternative is to use a fuel pump. The fuel can be pulled up through the in tank fuel pump.
There may be some information here that you can apply to your newer model. Particularly in post #14.

SDB110,
So, how many gallons of gasoline did you put into your Sprinter's diesel fuel tank?
There is no shame here, most of us have done this at one time or another, the critical
thing being WHEN you realized that you put the wrong fuel in the tank, and what you
have done since.
Did you turn on/try to start the engine BEFORE realizing that you put the gasoline into your
diesel fuel tank........this is the WORST scenario as some of the gasoline may have been pumped
(by your in tank booster pump) into the fuel filter and on into the high pressure fuel pump and
the fuel rail (s).
If you realized mis-fueling BEFORE turning on the ignition/trying to start the engine, which it sounds
like you may have done (at least we hope so) you can disconnect the fuel line from the in tank booster
pump, at the fuel filter and when you turn on the key to the first position, the in tank booster pump will
pump all the fuel in the tank out into a spare fuel container.
Or, if you realized the mis-fuel you could call MB Roadside assistance and they would probably transport/tow
your Sprinter to the nearest authorized MB Sprinter dealer where they would remove the fuel tank completely, get all the
gasoline out of it, ensure that it's completely clean and free of any residual gasoline or debris, and partially refill it with fresh dino diesel fuel.
If you don't try to start the Sprinter with gasoline mixed in the diesel and the tank is drained, there are no consequences
for the engine and it's fuel system.
If you realized the mis-fuel before trying to start the engine, and use the in tank booster pump to empty the tank you
will minimize the risk of damage to the engine and fuel system. A new fuel filter would be a good idea as the gasolline
could have stirred up or loosened some debris in your fuel tank.
If you tried to start the engine, and the gas/diesel mix has made it to the high pressure fuel pump and fuel rail
you are talking quite a bit of money and time to take the entire fuel system off the engine and inspect or replace
much of it.
Moral of the story here is to realize that you have mis fueled and mitigate the consequences by draining the fuel
tank before any of the gas/diesel mixture gets past the in tank booster pump.
Hope this helps,
Roger

A friend of mine bought a very nice top of the line 4x4 2500 extended Sprinter with every single option .
That's how story begins ...
Now it gets ugly - on like his 3rd tank he put gas in it. Drove it few miles and engine started shaking and died.
Called MB , they towed it , kept it for few days, then gave it back without changing any injectors or fuel pump. Just drained gas .
Hos insurance covered it but they added $10k to his loan

It doesn't cost $10,000 to drain gas, even with a tow. If all MB did was drain the gas out of the tank, how can it be said that his insurance covered the repair if $10k was added to the loan? Are some details to this story missing?

They said they will change : HPFPump , injectors, fuel rails , lines , tank.
Paper says they changed it, but the owner says he can't see that they touched anything

If that is correct its fraud.
There are ways to determine professionally if the items were changed, one of them being injector en coding & serial /prod numbers on the HPOP.
Even the rails have durable labels on the underside giving PT# & Prod dates.
If there is suspicion, talk to the shop general manager and ask pertinent questions. Be insistent, & ask for copies of their internal requisitions to substantiate the R/O consumption.
I used to do this as a zone rep in another life and for an attorney here in Denver.

If there is resistance then I suggest a letter from attorney as much as I abhor this approach, and get an independent INFORMED inspection done..

That guy won't do that . He lives in SC , bought his Sprinter in L.A. and put gas in NM He had a Promaster that he traded in

Well I wrote the post in abstract based upon limited info and so much like any post & its written information.

Now from experience putting gasoline in a diesel fuel tank isn't the end of the world as some might suggest.
Essentially gasoline has the same molecule train as diesel, just rearranged differently so it doesn't burn too well.
So you get an acrid exhaust stink & limp mod-ing.
Really boiled down its what you do to the engine & its FIE system. That means what immediate steps are taken to rectify the issue using the term sooner or later! Later being the operative word here.

My business has done "oudles "of these "repairs" and the real beneficiary is our shop's waste oil heaters.

We have set procedure, and a hose with a male barbed adapter. Attached to the main fuel line, and then cycle the ignition switch auto pumping the tank out until its as "dry" as you can get. That will leave about 2 gallons dwelling around the pump bucket "tops".
It take an average about 20 minutes to empty it.

Then bung in a good lubricity additive like BG245 or Stanadayne Performance Plus, followed by a full ish tank of diesel. Any residual gasoline will be diluted to no real concern.
Throw out the fuel filter(s)--& replace!
One on a Sprinter, Several on other brands and do a quick rail & line purge plus bleed up, preferably using a fuel pressure to see what pressure we get from the lift pump working.
If its to spec don't sweat the small stuff!
Go for a fire up and then a test drive .
In 999,9999% of the time it will be fine, BUT we did encounter one specimen that was driven about 250 miles, ignoring the loss of power !
Now that did the injectors & HPOP in, and we couldn't raise rail pressure to enable a start.
So again the word LATER is operative here!

So a fixed shop rate of 2,5 hours, one fuel filter (Sprinter) , one bottle of additive, & 20 gallons of DERV.
Not a serious wallet dinger!


The real issue is water & crap in bunkered fuel at gas stations!
Now that really does do expensive damage in a short space of time and a real wallet flusher!
But that is something else & quite a different set of circumstances prevailing.
