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.
