[Efficient Filtration]: The GDUKOP TP3018 fuel filter, paired with the 12642623 filter head and sensor, delivers efficient fuel filtration. Its multi-layer filter media boasts a 5-micron filtration rating and 98% water separation efficiency, working effectively to remove dust, rust, particles, and—most crucially—water from the fuel, thus safeguarding the engine against potential damage
[Easy to Install]: As a direct OE replacement, this filter is simple to install. When using the TP3018 fuel filter housing for 6.6L Duramax trucks, make sure to press the priming pump vertically during the first use. Note that some priming pumps may have a small amount of fuel leakage initially after installation—this is normal, as the O-ring inside the priming pump hasn't been lubricated by fuel yet. To resolve this, you can disassemble the priming pump and apply grease to the O-ring
[High Quality]: Stable quality ensures one-time installation and ready use, avoiding repeated hassle. Upgraded internal structure with premium aluminum base, quality filter and rugged water sensor. Made of high-quality materials, with multiple sealing tests and 100% inspection, meeting/exceeding OEM standards. Durable, reliable, long-lasting. Good heating performance; for no heating, just pull out the large plug (no filter head plug removal needed)
