Using this Duramax fuel filter housing kit is easy. First, find the location of the stock cartridge filter base in your 2020 - 2022 Short Bed L5P Duramax. Remove the old filter base carefully. Then, install the new kit in the same location using the provided OEM - style quick - disconnect fuel line fittings. It's compatible with stock trucks, so no tuning is required. When it comes to maintenance, the kit increases the time between filter changes, but you still need to keep an eye on the fuel filter. Replace the Donaldson 4 - micron fuel filter and water separator regularly. The 1/8' NPT port allows you to monitor fuel pressure, which can help you detect any potential issues early. In cold weather, the kit ensures the fuel flow path across the PTC heating element, so it works effectively. Remember, this kit replaces GM Part #13543066, so you don't have to worry about compatibility with your vehicle.
