My owner's manual came off of ebay, and it was for a '90 model (curiously, all of the other books were in the car, and were correct). The '90 book shows a 23.8 gallon tank, with a 3.3 gallon reserve. Is this the same as the '86 model? I only ask because even when I fill up and the reserve light is on, and I have driven on reserve for a while, it only takes 17 or so gallons to fill up.
Thanks, and God Bless,
