Was it only doing it when cold? Maybe fuel gelling? Filters would be a must.
Gelling
This is when diesel fuel turns to a gel-like consistency at temperatures approaching the products cloud point value. Untreated fuel will form large wax crystals which lead to the wax becoming so dense that it then drops out of solution triggering unexpected downtime. This thicker substance cannot pass through the fuel filter, so the engine may run intermittently, or may not start at all.
Water
Water is diesel fuel’s number one contaminant. It is likewise the number one issue fleets wrestle with on a daily basis and not necessarily just in the winter. Water can and will be prevalent in fuel dispensing systems by virtue of the handling and storage of the fuel. Vents breathe in atmospheric air into void tank space which starts the phenomenon. Water in fuel can freeze at temperatures below 32 degrees Fahrenheit blocking fuel lines and disabling water fuel separators. If it doesn’t’ freeze it can and will become a breeding ground for microbial contamination which independent of itself can ravage a fleets operational balance. No chemistry can replace what a good housekeeping program can do for establishing a strong prevent defense against water contamination. It is recommended throughout the year to keep tanks full to prevent condensation from forming inside the tank and lessen the chances of water getting in the fuel line.
