Replace Primary Fuel Filter

What happens here

Locate the primary fuel filter, often a spin-on type near the engine. Place a small container or jar beneath it to collect drained fuel. Use a wrench to loosen and remove the primary fuel filter. Observe the drained fuel for any signs of contamination like water or sediment. The video shows significant water at the bottom of the jar. Apply a label with the date and operating hours to the new Bosch branded fuel filter. Pre-fill the new fuel filter with fresh diesel fuel. Apply a thin coat of fresh diesel fuel to the gasket of the new filter. Install the new filter by hand-tightening it until snug, then give it an additional quarter to half-turn.

Goal: Install a new primary fuel filter.
