No, a bad sending unit has no bearing on anything but the fuel level indicator on the dash. That's it's only function, but it's a good time to fix it while the tank's down. One thing you could try is drive it until it stalls out, then quickly unhook the fuel line into the carb, direct it into a container and have someone crank the engine while you watch the line. If the sock is clogged you'll be getting no, or very little flow during crank; then once it sits for a few minutes (particles fall away from the sock?) you'll again have flow. Just an idea to gather information, but don't set the Scout on fire with raw fuel and a hot engine.
