Fuel Filter Plugged with Black, Scummy Residue
Problem: Bacteria in TankTreat with bio
Believe it or not, micro-organisms can thrive in a diesel tank with a little bit of moisture in it. If the fuel filter is plugged with a black scummy substance, or if there is a dark scummy substance or “carpet look” in the tank, you likely have a bacteria problem.
To combat this, use the MP8 Biocide available from Lubrication Specialties by calling 1-800-341-6516. After you treat with the biocide to kill the bacteria, follow up with back-to-back treatments of Diesel Extreme to clean out the system and replace the fuel filter.
If you have any questions, feel free to contact one of our diesel experts.
