Fuel pouring out inside engine bay

[JonnyW97]

Hi all,

I tried to turn my car on yesterday and after turning over for a while it stalled twice followed the smell of petrol.

The car does run but it absolutely pisses fuel out, the closest I could identify its coming out from is as below, the bottom of the photo is the radiator.

Does anyone have any idea where it might be coming from, or have a manual which shows where fuel goes in to the engine so I can identify which hose the problem one is.

Follow the fuel lines from where they come into the engine compartment to the fuel rail/injectors.

I'm afraid I'm not sure which lines I'd be looking at for this. Or what the fuel rail looks like. I'm quite new in the process of trying to sort my own car issues and unfortunately I dont have anyone to teach me.

No worries, everyone has to start somewhere. What engine do you have?

Cool, you have a high pressure fuel pump on that, so i would start around that area. Here's a video that shows a leak from one and where it's located.

If you get someone to crank the car while you look, you may be able to see the problem. Obvs be mindful of the fire risk, and if you're new to working on cars then make sure you keep your fingers and loose clothing away from the radiator fan and any belts and that kind of thing. If the leak isn't from that high pressure pump, you can follow the 2 fuel lines that come out of it. One is the supply pump from the tank, the other will be the outlet from the pump to the engine.
DO NOT put your hands anywhere near the pump when someone is cranking the engine or the engine is running. If the leak is on the output side of the pump, the pressure can be high enough to inject fuel through your skin into your bloodstream.

Have a watch of this video too. Much easier to see the fuel rail with the manifold removed.

Sorry, but it sounds like a high pressure rail securing bolt has had its head snap off, so not much that you can do about that, needs transporting to a proper VW Group Indie for them to strip down, replace any damaged injector seals and their retainers, replace all 4 bolts and torque them to the correct value.

This is not a wear and tear issue if it is a snapped bolt head, it is due entirely to the Skoda engine plant assembly equipment being faulty when that engine was initially built.

After the repair you really do need to report this on the DVSA reporting system online as VW Group marques in UK have told the UK Gov dept responsible for car safety that this is not a fire safe issue - and the dumb lazy UK Gov dept agreed with them.
