How to remove incorrect fuel from CLC 350

[DingDong]

Good day,

I filled up the tank with aprox 20L of diesel,
How do I go about emptying the tank and is anything else necessary or can I just fill it up again afterwards with the correct fuel ?

Assuming you didn't start it I'd syphon out what I could & then brim the tank with petrol

As above then fill again when room forc1/4 tank

You could disconnect the feed into the fuel filter,
Connect a pipe to that, and into a container.

Each cycle of the ignition should give 15 seconds of lift pump activity.
you'll be surprised how fast the tank empties, and to empty.

Sorry ,but

I once put £10 of petrol into my virtually empty (old school) diesel Astra. It started no problem & drove 4 or 5 miles home without problem. The following morning it refused to start. It was only cos I had receipt that I knew what I'd done. I drained the tank & put a gallon of diesel in .... it started! I brimmed the tank & had no further problems.

They were a bit different back then…

Think you’ll struggle to syphon - they’ve made it difficult to “suck diesel” these days.

I’d look at @M80 ’s suggestion above

You can add petrol to diesel. This lads added diesel to petrol. Big no no.

but diesel is the lub for the fuel pump. If it's just petrol in a diesel, the the pump fails & then costs ££££££££££££££s.
If you put diesel in a petrol, it just won't run.

OK then ..... remove the fuel from the tank as best you can ......

they were ..... hence the 'old school'

I think but not sure, this has a saddle tank and with only drain one side via the pump.

I put 17 litres of petrol in my diesel Laguna before I realised what I was doing. Stopped and finished putting 35 litres of diesel in the car. It drove okay but after 40 odd miles it didn't run that great but still carried on. Finally topped up with more diesel and she's still hoping strong.
I do put diesel in my old petrol cars every so often but only around 5 litres. Keeps the residual build up of petrol deposits at bay inside the carburettors. Though don't tend to do this much now with diesel prices.

I thought the nozzle was too big.

There's no way you can get a diesel nozzle into an unleaded petrol filler "orifice".

Curious to hear how the OP managed this ?

Maybe old car pre unleaded days. They had larger filler opening.

Depends on ratios . 10 litres of petrol in a diesel tank brimmed with diesel would run . Plenty have done it and realised ,brimmed it to the top and once again when it's at halfway. Not sure it will work on today's engines mind.

He does state " old " . Cars . Or possibly decants to a Jerry can with a nozzle ??

Putting moderate amounts of petrol in diesel was, I believe, noted in my 300gd as an aid to winter starting. I accidently did that once and discovered the fact by seeking a solution from the handbook.
However modern fuel pumps as previously said are lubed by the diesel. And I know that when the lube fails the pump head often snap off internally. Seen it on international motors a few times.
