FC quit running

[Dan Darst]

Thanks for your comments Dan, they fit perfectly with what I am
experiencing. I am doing last resort procedures. Last night took me five
hours to remove the two foot long flexible line running between the copper
line and the filter on the cat. It looks original and in excellent
condition, so I was/am disenchanted with the hope that this is the problem.
In the next two hours I will get a new line made and install and run test
probably tomorrow.

Appreciate very much you sharing your experience.
