    I have a '67 V6 with the large original-type inline fuel filter located over the fuel pump.

    Last weekend, I noticed gas dripping from the fuel inlet line at the carburetor (which took the paint off my intake manifold - Doh!!!). Turns out the gasket behind the large inlet fitting needed replacing. Glad I caught the leak when I did, as it could conceivably have caused an engine fire.

    There is currently not a second filter installed in the fuel inlet fitting. Since I couldn't find a replacement gasket by itself at the LAPS, I bought a new inlet fitting and gasket on eBay. These came with the small internal bronze "filter" (if you can call it that), inside gasket, and spring - pictured here on a diagram of the 2G carb showing a different type of internal filter:

    Given that I already have the larger inline paper filter, is there any point in installing this bronze filter as well, or should I just leave it out?

    If I should install it, in what order should the parts be installed? Also, which direction should the open end of the filter face?

    Last line of defense, I would just install it.

    Leave it. The engineers put it there for a reason.

    Different situation but I took mine out and the bowl started to sporadically overflow.
    Put it back in and no issues since.

    Like others have said it's there for a reason.The order you have pictured is correct with the open end toward inlet fitting. I have found more than a few that were plugged and doing there job.Some of our newer jeep owners may not be aware of this filter as it hides inside the fuel inlet fitting. Be sure to check and replace during tune-up . Filters should still be available locally . mike

    Possible the filter acts as a baffle at the entrance to the needle, minimizing float bounce due to fuel surge. I'd leave it in.

    I learned something new today! I never realized that was a bypass spring. I thought it just held the filter snug to the inlet fitting, but never thought it allowed a bypass if the filter clogged.
    Pretty neat! -Donny
