I posted several months ago about a slight leak on the fuel line at the point where the rubber hose meets the metal flared fitting, specifically at the crimps. I temp. fixed it by installing an alligator clamp around the metal fitting and just tightening the $hit out of it. It has worked for probably 7 months, but now it is getting colder and I suspect the metal is contracting causing the problem to resurface. Yeah, I know, just replace the line...try $500.00 plus without labor! My tech looked at it awhile ago and said, off the record, my repair was fine unless the leak showed up again. So my question is, can I just refit and tighten the clamp again or is there another way of remedying this problem without having to replace the line. The leak is very, very small.
