Stop there. The coming few minutes settle it far more than anything else: petrol in a diesel that has not run usually comes down to clearing and flushing, right there. Anywhere you are around Hook, here is how things go from here. ## Motor off: minute one with petrol in a diesel Before anything else, the following — in this sequence. - Ignition off, keys out. Switched on, the ignition can prime the system — and priming is what moves petrol out of the tank into the parts it harms. - Topping up with diesel seems like it thins the issue. It doesn't: nothing gets out, and that tank just holds more of the same. - Make the car simple to see first — hazards on — if there is moving traffic anywhere close to you. - Off the petrol pump by hand. On a forecourt, ask the staff to help you roll the vehicle clear of the pump. Do not crank it to move it, however short the way. - Hold on to the till receipt. It says which fuel was put in and about how much, which is the first thing we will ask. On the A1(M), under 25 miles from Hook, the next junction is the location to leave the car; anywhere, the first sensible place to stop. Do not press on to the services. Then go back to stage one. ## The fork in every Hook fuel drain: has it run yet? What happens next rests on one answer, and only one. If it has not once been started: - Just your tank has petrol in it so far. - The job is a drain and a flush, normally done where your car stands. - Being here is the best case — which is the whole point of stage one. If your engine has been run, even for a moment: - Out of that tank, through the filter, into your lines: that is how far the petrol has travelled. - Run it further and the petrol gets to your injectors, having gone through the fuel pump first. - The further it went, the bigger the job — the fuel lines, the filter, and now and then more besides. That line falls there since diesel lubricates the high-pressure pump and the fuel injectors on its way through them — and petrol does not. In that tank, sitting still, petrol does no harm. Pump that petrol, though, and it wears the very parts that move it. ## Calling about petrol in a diesel from Hook: what to have ready A van that circles versus a van that finds you: a little preparation is the difference. - Where you are. A postcode starting PE15 0 is the ideal place to start. - The street or the car park. A road name is a help — Hook Drove, or wherever you have pulled up. - Name a car park by what it serves — the one outside Co-op Food, for instance — and it's much quicker to find. - That it is a diesel, along with the make and model of your vehicle. - Say which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Hook. - The quantity: your receipt's litres, or otherwise how long you had the nozzle in. - If it's run, how far and how heavily — as well as whether it has run at all. - Hire or company car? Some contracts need the owner's go-ahead for the work, and sorting it before our technicians arrive is quicker than after. Next, 0333 366 0103. Not time-critical, the car parked at home with nowhere to be? Then works as well. ## Waiting for a fuel drain in Hook: what to do During the wait, the damage comes from well-intended help — so these matter. - Where the car has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the car. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a few yards. - None of that gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond the tank. Don't drain the car yourself. - Not for your radio, not for the windows: your ignition remains off. ## Step by step: the fuel drain when our van arrives - Three questions. What got in, how much, and whether it has run. The answers set the job, which is why our price comes after them but not before. - Next that tank is drained, so the contaminated fuel comes out. - Petrol that has moved beyond your tank sits in the lines if it ran, and your lines are flushed to clear it. - Then the fuel filter: swapped where there is a usable one, cleared where there is not. - Bleeding the system comes after clean diesel is in. - The first start on new diesel. When priming is done, your engine is started and we make sure that it runs smoothly. We wait until it is running on new diesel. It's very rare for a car caught soon to be left with lasting damage, and normal use resumes at once. ## Back on the road around Hook after the fuel drain - After it has been started on fresh fuel, there is nothing unusual to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and call us back. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to your documents. - Next time, read the pump. The label, not the colour of its handle. ## About Hook Hook is a small hamlet situated on the riverside in Cambridgeshire, with a low elevation of around 5 metres.
