Default Fue smell inside cabin

I'm getting a raw fuel smell inside the car but only when the windows are down or when the sunroof is open. Which leads me to believe it's coming from the engine bay and not the fuel lines inside the car.

I pop the hood and can't see or smell anything by the fuel lines, fuel filter, or injectors. Is there any safe way to find a fuel leak? BTW this started after I swapped the motor so I checked everything that was disturbed during the swap, and replaced every fuel hose while the motor was out. Any ideas? Thanks in advance.

Nope , full cats. The smell is raw fuel though, not exhaust so im not sure the cats would make a difference or not.

Have you replaced the fuel lines under the intake manifold? The early subarus had that issue. It usually leaks right under the passenger intake runners.

Just the reinforced rubber hoses. All the hardlines were reused.

Any tips on "safely" finding a fuel leak, other than smelling for it?

I would have replaced the hard lines too. The hard lines could have a small enough crack where fuel could leak. You should be able to see/smell the fuel by just having the fuel pump purge.

Do you still have your vacuum canister assembly hooked up?

The canister is physically connected to the fuel tank, but none of the solenoids and valves are hooked up to anything. Would that be the problem? Where should I plug up the lines? I didn't think the canister would vent into the atmosphere if none of the solenoids were powered.

wash your engine bay with cleaner, if you're leaking fuel somewhere.... at least you won't have to worry about having your car go up in flames till you figure it out.


if you are REALLY smelling fuel, and not buring oil... then you have bookoo problems.



find the leak.
