Buying Guide Before Purchasing Best Fuel Filter For Duramax Diesel

How to Pick a Fuel Filter

The obvious first step is to make sure you choose one that is designed to fit your vehicle and application if it’s a stock replacement, that usually means picking up your vehicle from the website’s virtual assembly garage or checking the filter manufacturer’s site or one of the many common exchange guides.

If you add a filter to a vehicle that doesn’t have one, or one with a modified engine or fuel system, things get more complicated. The size of the lines running from the tank to the engine matters here, type-wise.

Rubber and metal hoses use different end fittings, just like common AN style lines. You need the right end and the correct diameter, with the last size to help ensure that your lines can move enough fuel to keep the engine fueled.

If you are using a non-standard fuel, such as diesel or E85, make sure your filter is designed to handle those products.

When and Why to Change Your Filter

Over time, fuel filters will become clogged with small particles, reducing flow and potential engine performance. A clogged filter can cause your engine to run poorly or not start. Forcing you to work harder can even kill your expensive fuel pump.

For the recommended change interval, check your owner’s manual, which should tell you when the filter needs to be changed. If the manual doesn’t say so, many manufacturers recommend 30,000-mile or two-year intervals (whichever comes first).

Consider shortening that interval even more if you are operating a high-performance engine or driving in excessively dusty conditions.

How to Change a Fuel Filter on a Duramax

Fuel systems can be very high pressure, and gasoline and diesel fuel are contaminants, so proper care when replacing them and proper disposal of old filters are essential.

To relieve fuel pressure, remove the fuel pump fuse and try to start the engine. This should remove the pressure from the line, although the motor is likely not running. Find your filter, which is often located under, near the middle of the car or truck, although occasionally under the hood, especially in diesel trucks.

Remove the old filter holder and then remove the lines leading to it. Fuel will spill, so collect it in a suitable container for reuse or proper disposal. Look for an arrow on the existing filter, place the new one with the arrow pointing in the same direction.

Reconnect the lines, brackets, and cables, then reconnect the fuel pump fuse and restart the engine. Because some of the fuel has drained, this may take a little longer than usual. Dispose of the used filter by local environmental regulations.

Be aware that fuel is highly flammable, and fumes are toxic. Change the filter away from any spark or ignition source and do so in a well-ventilated area. Especially in the tight space under your car, gas fumes can quickly become overwhelming, which could lead to dizziness or even death.
