i have a 93 legacy l with the ever popular leaky fuel filler pipe.  the car is just a beater with 200,000+ miles, and i use it on the weekends for hauling trash, etc.  my question is this.  instead of sticking over 100 bucks into getting a new pipe, is there anyone who has used a rubber hose to repair this?  i am not sure if it is flexable enough, or even possible, but thought i would ask around.  i may sound cheap, but i would rather not stick a whole lot of money into this car.   
  
if someone has done this, or thinks it's possible, can you suggest what diameter hose to use?  thanks for the help.
