Yo Mike,<br />If your fuel lines are showing signs of age, the best thing ta do is go ahead and replace them. You could use a "tee" and vacuum gauge and look for the leak(s) but ya might as well do it right and then not worry about it anymore. That's what Hooty would do anyway.<br /><br />c/6<br /><br />Hoort
