Hey Josh, I saw on your BIG TEN resto that you did just what I do with the fuel line. I've added a further refinement attaching a simple bracket made from a coat hanger using the top hole for mounting the choke cable on the outside of the carb. It always bugged me I couldn't get the line to stay perfectly level.
The clear filter is a nice window to your fuel flow, when things go wrong. I've routed them various ways...never paid a whole lot of mind to it. I've noticed with a longer, droopy line, it pisses less fuel if you pop the line off the carb for maintenance. The flat line always drains iteslf, after the shutoff valve. (I have carbs on and off way too much as of late)
