If your jeans smell like gas, you have a leak down low, possibly a cracked hose, usually near the clamped ends...airflow is blowing it onto you which is NOT a good thing. Your bike is old enough that it probably needs most all the hoses replaced just as a precaution. Measure all the lengths you need and if there are sharp bends, sketch a rough outline of the curves. You may need "formed" fuel line hose, so your friendly neighboorhood autoparts store will have regular 1/4"-5/16" hose or heavy duty (read stiff) fuel injection reinforced bulk or preformed hoses you trim to fit. Bring the old hoses with you...if you can, and replace with worm type clamps.
