Check For Fuel Contamination

Obtain a fuel sample. Visually examine fuel in a clear container (including bottom of container) for particles, clouding, or liquid contamination (such as water). If fuel sample is okay, go to next test. If fuel sample is contaminated, replace fuel filter. Clean and/or replace fuel system as necessary. Ensure fuel is clean and go to next test.
