I found something odd today on my 8N fuel line when I was trying to diagnose what I believe to be a fuel flow problem.About 5 inches up the line from the carb intake, there is a 3 inch section of rubber hose, and then the copper fuel line continues back up to the output of the fuel sediment bowl. This hose is secured to the copper line with hose clamps. I thought this was by design, as some sort of vibration control mechanism or strain relief for the long length of copper tubing. But my I&T manual shows this should be a solid copper line from the fuel sediment filter to the carb. AND... If I remove the short section of rubber tubing I notice that the now free ends of the fuel line are flanged. As if it used to have some sort of a compression fitting attached like a second fuel filter. Or the previous owner could have just rigged this up this out of spare tubing and copper parts when his fuel line went bad. I dunno. The rubber tubing is coming apart. It needs to be replaced. Should I replace the entire fuel line from the sediment bowl to the carb? Or is there some well-known fuel filter that I should put back inline here?
