1. Prepare Your Vehicle

Park your Peterbilt 389 on a flat surface. Make sure the engine is off and cool. Safety is paramount!

2. Locate the Fuel Filter

Find the fuel filter. It’s usually situated near the fuel lines, under the chassis. If you are having trouble, consult your owner’s manual.

Before you proceed, it’s essential to release any remaining fuel pressure. You can do this by removing the fuel cap from the tank. Just be cautious!

7. Check for Leaks

Before putting everything back together, turn on the engine. Let it run for a few minutes and check around the fuel filter for any leaks. If everything looks good, you are on the right track.
