    Fuel Tank Outlet Leak

    Any suggestion on stopping a very slight leak at the tank outlet. It is coming from the strainer nut and not the fuel hose connection. There is a new
    copper crush washer. It is on pretty tight and I am concerned about stripping the threads if more force is applied.
    Thanks

    RectorSeal Tru-Blu pipe dope lightly applied works.

    Thanks Mick
    I checked their site and they don't mention gasoline. My concern would be that it dissolves and ends up in my fuel system. Maybe that your comment about light application?

    Tite Seal worked great on my RS tank fittings. Can act as a filler.
    I've usesd Gasoila as well.
    Aircraft Spruce sells Tite Seal. Gasoila can be found in most plumbing supplies.
    Neither are hardening.

    Apply pipe dope only to male threads so it is never pushed into the joint as would be if applied to female threads, just smear on the gasket washer lightly, Gasoila is fuel resistant as in Sithot's post a good choice!.

    I've had excellent luck with applying GREEN Loctite around the fitting after it is in place and tight....just give a spritz of brake kleen to clean the fitting, quick blast of air, and then apply. No harm in trying this first to avoid having to undo the fitting.

    Thanks for the tip. Maybe I'll try the belt and suspenders method.
