Fuel Line buying guide
Why replace this part?
Fuel lines carry fuel under pressure from the tank to the injectors and return excess fuel to the tank. A cracked or corroded fuel line is a serious fire hazard and causes fuel pressure drops, leading to lean running and engine stalling.
Signs you need a replacement
- Strong petrol or diesel smell inside or under the car
- visible fuel stains along the underside
- fuel pressure drop under load
- engine stalling during hard acceleration
When to replace
No fixed mileage interval — inspect for corrosion and cracking every 50,000 miles or 5 years. Rubber flexible sections are the most vulnerable.
