    Hoping you all can help. I'm new to the boards and a few months ago bought my Grandfather's 02 Tundra. I recently returned from vacation where the truck sat and it looks like a mouse or small rodent bit through one of my fuel lines underneath the truck. I read online that these tubes are manufactured with some amount of soy, so that draws rodents in? The truck starts, with a little hesitation, but sprays fuel out of the leak when running obviously. So it's been sitting since I got home, I noticed it a few days ago.

    The pictures provided show the line assembly (3 tubes) that feed into the fuel tank.Misc 1.jpg Line Assembly.jpg The middle one, that looks shiny and covered in gas has the small leak. The leak is circled in the pictures.
    The additional pictures of the connections show both ends, one where it ties into the fuel tank with the red connector and then into the other part (fuel connection 1.jpg). Line Connection.jpg Line Connection 1.jpg

    I've been researching online about what part number this is. P/N 77209-0C010 (picture attached)77209-0C010.jpg was my first inclination, but am unsure. P/N 77340-34010 looks like the whole assembly in my opinion. https://www.toyotapartsdeal.com/oem/toyota~valve~assy~fuel~cut~off~w~tube~77340-34010.html

    Additionally, is the replacement of this tubing as easy as plug and play? It looks like both connectors just pop off and on, something an average skilled guy like myself could do?

    Appreciate all of the help!
