My car has been just reeking of gasoline for the last couple of weeks. I'd looked around at the fuel hoses, because I just changed the fuel filter about three weeks ago, but everything looked fine. Today I stopped to get gasoline, and opened the hood to check the oil, and saw fresh gasoline running down the front of the engine, where it's dissolved all the oil that's usually crusted on the engine. From that I could tell pretty close to exactly where it was coming from, the fuel return line from the high pressure fuel rail, and when I bent the hose to see if there was a crack, it simply broke. It only leaks when the engine's running, which is why I couldn't find it previously. Luckily for me it broke right at the point where it pushes onto the metal fitting, so I popped off the clamp, removed the broken bit, unclipped the hose from the nearest guide clip so it could stretch over a bit, and put it back on.
This reduces the chances my car will suddenly catch on fire by like 95%.
It also increases my interest in owning an entirely electric car.

But what happens when you have electrons leaking all over your engine instead, hmm!?

Well that's a reason I hadn't thought of, for wanting an all electric car.
Hey, wait a minute. Is this the "*Spit Fire*"? Nah, that would be too appropriate.

Hah, that would be all too apt.
The Spitfire has a single fuel line that runs from the tank, to the filter, to the fuel pump, to the carb. You can't get much more austere than that.
The Subaru Outback, wowie. A fuel line forwards to an electric fuel pump, that goes to a first regulator, that goes to the high pressure rail, that goes to the second regulator, that goes back to the tank, and then a whole separate line that comes forwards from the top of the tank to the manifold to suck up gas fumes, and every one of those somehow has a set of lines going over to a vapor catalyst canister, and I think there's another loop between the two regulators that uses fuel pressure to control the first regulator. I've never understood what all that does or how it functions.
