On arrival in Dartford: what happens next
The drainer parks up, checks the vehicle has not been started and makes the area safe with cones and a drip tray. The fuel is pumped out through the filler or the fuel line into a sealed tank on the van, the lines are flushed, a few litres of the right fuel go in, and the engine is started and run until it idles cleanly. The contaminated fuel leaves with them.
What to ask on the phone before a drainer travels to Dartford
Most bad experiences with a fuel drain come from not asking these up front. Ask them all.
- What is the total, not just the call-out, if it is a straight drain?
- Do you bring clean fuel, and is it included?
- Will you dispose of the contaminated fuel, and can I have a note of it?
- Is there an extra charge at night or at the weekend?
- How much more if the engine has already been started?
What to do right now
- Leave the ignition alone — on many cars even unlocking it powers the fuel pump.
- Push the car clear of the pump if needed, with someone steering and the engine off.
- Call 01295 380724 and give the fuel, the amount and your exact location.
- Ask for the whole price, not just the call-out, and agree it.
- The drainer drains the tank into a sealed container and flushes the lines.
- Fresh fuel goes in, the engine is started and the waste fuel leaves with the drainer.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Dartford.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
How long does a drain take in Dartford?
Usually 45 to 90 minutes on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
How quickly can a drainer reach me in Dartford?
Usually the same day and often within a couple of hours. The operator gives you an arrival window on 01295 380724 before you agree.
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
