Anyone have a good visual of fuel system in engine bay?

    We have a 2013 prius v

    We just did a full egr system clean and husband said he was smelling some exhaust fumes this morning. No check engine light, nothing else seeming amiss, but want to make sure all the hoses and such don't have leaks and are connected properly. There was a lot of fussing around in the engine bay and we just want to cover our bases

    Before starting it up? FWIW, when I pop the hood on our '10 there's usually a slight "bouquet".

    Congrats on the job, btw. :)

    Thanks, he did a great job, I tried my best to help with the stupid cooler haha. We are seeing instant improvement in car performance, wish we'd known about that sooner

    Only off thing at this point is my husband says on heavier acceleration there is sometimes a fuel smell so I just want to make sure there's no leaks after that

    I wouldn't think you'd need to disturb the injectors or fuel rail. Maybe something amiss with the intake manifold? There's two PCV hoses on it; I know from personal experience if the main lower hose (from the PCV valve) is disconnected the car will flat-out refuse to run.

    There's also a hose running gas tank vapours back to the intake manifold, plugs in just below the throttle body, around 3 o'clock orientation. Again, not sure if the car would even run, with it disconnected.

    The egr system is flowing exhaust into the intake. Eg “Exhaust Gas Recirculation”. So if the egr cooler, valve or pipe is missing a gasket you can have an exhaust leak under the hood.

    It is much better to make instrumental measurements using programs and look at the engine operating parameters using them.
    Do you have the opportunity to use some kind of scanner or a special Techstream program?
