Answer
Answer:
Danger: fire hazard, take extreme precautions, several fire extinguishers at hand, a gallon of soap plus garden hose to scrub and wash away fuel spills.

The old fuel mixture you describe is unstable over time, and now must be removed.

#1. Drain all of the sludge from the fuel tank.

#2. Refill with five gallons of fresh fuel.

#3. Bleed one quart of fuel from the high pressure line at the fuel distributor.

#4. Bleed roughly one ounce of fuel from each injector.

#5. Try starting the car, it should run terrible for roughly half an hour.
