Problem: Spark plugs keep fouling up - Fuel problem

Could be that your fuel tank has microscopic particles of rust passing through the filter from the fuel tank.

Solution

• removed the fuel tank
• Take tank to car wash (if you don't have the equipment at home) and give it a good spray with the high pressure hose. Don't be surprised if you remove a bucket load of rubbish
• Filled tank with molasses and water and let it sit overnight, to make it more effective this person hooked up the compressor and put the hose in it, giving it a steady flow of air that circulated the water and molasses overnight
• Next day empty the tank, and the drop a bucket load of bolts into it and shake it for a while, cleaned it out, wash it out and put it back in the car
• Fit clean or new spark plugs
• Take car for a drive, if you still have problems then you know its not your fuel tank
