The fuel path runs tank → lift pump → filter → high-pressure pump → injectors, and contamination only moves along it under power. Stationary, the problem stays in the tank where it is cheap to remove. Under power, it spreads into parts that are not. ## Step by step Do not start the engine Before the key turns, the problem is in one place. After it, it is in four. That single decision is worth more than anything else on this page. - Stay put if it is safe to Do not try to reach home, a garage, or a quieter spot. Every mile driven moves contamination further down the fuel system. - Get clear if it is not On a verge or a hard shoulder, leave the vehicle and stand behind the barrier. Kit can be replaced; you cannot. - Ring 01293 248666 Have the registration, the fuel type and an idea of the quantity ready. The full price is confirmed on that call, not on arrival. - The technician works where you are Extraction, line flush, fresh fuel, prime, run-up. Everything needed travels in the van. - Paperwork and away You get an invoice and we take the contaminated fuel away as controlled waste, properly consigned. ## The full page for this - Diesel in petrol in Middlesbrough ## Related searches - Diesel in petrol car - What happens if you put diesel in a petrol car - Diesel in a petrol car - Put diesel in petrol car - Putting diesel in a petrol car - Can you put diesel in a petrol car - Diesel in petrol engine - What happens when you put diesel in a petrol car ## What drivers tell other drivers 4.8 stars, 2,190 Trustpilot reviews.
