Dirty and Plugged Up Fuel Tank

Lack of attention here will leave you stranded on the road!

You might be amazed at just how much crud can build up inside an old diesel fuel tank.  If the car has only been running diesel fuel, much of what you might see is caused by algae growing in the tank. Over time it will turn into black colored particles that will start showing up in your clear plastic pre-filter.  If the car has been running biodiesel or SVO the problem can be even worse.
