Thanks for your input "chpence1". I agree that a schematic would be very helpful. I may try and put some fuel in the main tank, with a large amount of preservative, and see if that makes a difference.
The part that confuses me, did the techs take that 5 gallons of fuel back out of your main tank and that is why it is still not working??
