Pause there. Drained and rinsed, just where it sits: that is generally all an unrun diesel with petrol in it needs. Whether it remains that simple depends on the minutes to come far more than on everything else. From here on, in order, wherever you are around Pont-y-felin: ## Petrol in a diesel? What to do in minute one Work through the following in order, before you do anything else. - Pull the keys out. Even your ignition by itself can prime your fuel system, pulling petrol out of the tank to precisely the parts it harms, so keep the car off wholly. - Don't top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture. - Hazard lights on. If you're anywhere near moving traffic, make the vehicle simple to see before you do anything else. - The attendants will generally help you roll it away from the petrol pump. Let them, then roll it by hand — never on your engine, even for a couple of yards. - Hold on to your receipt: the grade and roughly how much are written on it, and they're what our technicians ask about first. If you were still driving when you realised, stop somewhere sensible rather than pushing on for the services — on the M4, under 10 miles from Pont-y-felin, that means the next exit. Stage one comes next. ## Has it run yet? The fork in each Pont-y-felin fuel drain From this point on, everything comes down to a single answer. If it has not once been started: - No place but your tank: that is where that petrol still is. - The job is a drain and a flush, normally done where the car stands. - This is the best spot to be in, and the reason step one counts. Engine run, however briefly? - Petrol has been pulled from that tank, past your filter then into your lines. - The high-pressure fuel pump and the fuel injectors see it too on a bigger run. - The further it went, the bigger this job — the fuel lines, the fuel filter, and now and then more besides. The reason the line falls there: diesel protects the high-pressure pump and your injectors as it passes through them, and petrol does not. A tank of petrol, left still, damages nothing. Petrol being pumped is grinding down the parts that move the vehicle. ## Pont-y-felin, petrol in a diesel: have these prepared before you call Whether the van goes round or finds you depends on a little planning. - Your location: a postcode beginning NP4 0 serves best. - The street or the car park. A road name helps — A4042, or wherever you have pulled up. - Car parks are located most easily by what they serve: say the one at Co-op Food, and it's straightforward. - Make and model of the car, and the fact it's a diesel. - What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Pont-y-felin, so tell us which. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - Has it run? If so, say how far it got, and how it was driven. - Hire or company car? Some contracts need the owner's go-ahead for the work, and sorting it before we turn up is quicker than afterwards. Phone 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Pont-y-felin: what to do The wait is where well-meant help does the harm. Hold to these. - Stay with the car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: no one starts it. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - A DIY drain misses the fuel already gone beyond your tank, and siphoning petrol by the road is dangerous too. - Leave the ignition off — your windows and your radio too. ## Van arrived? Your fuel drain, one step at a time - Three questions. What was put in, how much, and whether it has run. Those replies set the job, which is why our price comes after them and not before. - Then the tank is drained, and the tainted fuel is taken out. - If it ran, the lines are carrying petrol that has moved beyond the tank — so they're cleaned. - Cleaned, or changed if the car has a workable one: the fuel filter is seen to next. - Priming follows after clean diesel is in. - The first start on fresh diesel. When priming is complete, the engine is started and we make sure that it runs smoothly. We stay until it's running on new diesel. Your car goes back to normal use right away, and permanent damage is very unusual when it has been noticed quickly. ## Pont-y-felin, after your fuel drain: back on the road - Started on fresh diesel, it asks nothing unusual of you. Just drive normally. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - Your documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, read the pump. The label, not the colour of the handle. ## About Pont-y-felin itself Pont-y-felin is a suburban area in Torfaen, situated on the riverside at an elevation of 87 metres, with detached housing being the predominant type of accommodation.
