Jeep Wrangler: REFUELING THE VEHICLE — DIESEL ENGINE (IF EQUIPPED) / Bulk Fuel Storage — Diesel Fuel

If you store quantities of fuel, good maintenance of the stored fuel is also essential. Fuel contaminated with water will promote the growth of “microbes.” These microbes form “slime” that will clog the fuel filtration system and lines. Drain condensation from the supply tank and change the line filter on a regular basis.


When a diesel engine is allowed to run out of fuel, air is pulled into the fuel system.


Do not open the high pressure fuel system with the engine running. Engine operation causes high fuel pressure. High pressure fuel spray can cause serious injury or death.
