Important: Please verify your vehicle's OEM part number before purchasing. This assembly is a high-precision component designed specifically for diesel filtration. Ensure professional installation to prevent air bubbles in the fuel line, which can cause engine stalling or starting issues.
The 23300-78237 Fuel Filter Assembly is a premium-grade filtration solution engineered to protect your engine's fuel injection system from harmful contaminants. Integrated with a high-efficiency filter element, a durable primer pump, and a transparent sedimenter bowl, this unit effectively removes water, dirt, and microscopic particulates from diesel fuel.
Crafted from reinforced aluminum alloy and high-grade synthetic media, it ensures optimal fuel flow even under extreme pressure. Its robust design is built to withstand the rigorous vibrations of heavy-duty hauling, extending the lifespan of your injectors and maintaining peak engine performance.

Dual-Stage Separation: Features an advanced water-in-fuel (WIF) sensor port to detect moisture before it reaches the combustion chamber.
Easy Priming: The integrated hand primer pump allows for quick system bleeding after filter changes, reducing downtime.
OEM Fitment: Precision-manufactured to match original factory dimensions, ensuring a "plug-and-play" installation without modifications.
Corrosion Resistance: The outer housing is treated with an anti-oxidative coating to prevent rust in humid or coastal environments.
Q: How often should I replace the filter element in this assembly? A: We recommend replacing the filter element every 15,000 to 20,000 kilometers or every 6 months, depending on the fuel quality in your region.
Q: Does this assembly come with the water-in-fuel sensor? A: This unit includes the housing and primer pump. The sensor port is standard, but the electronic sensor itself is usually sold separately or reused from your old unit.
Q: Is this assembly compatible with Biodiesel? A: Yes, the seals and gaskets are made of high-grade Viton/Nitrile rubber, making it compatible with B20 biodiesel blends.
Q: Why is fuel leaking from the bottom drain valve? A: This usually indicates the O-ring is worn or the valve was over-tightened. Ensure the drain plug is hand-tightened only to maintain the seal integrity.
Q: Can I use this for a custom marine engine setup? A: While designed for trucks, it can be used for marine diesel engines provided the flow rate does not exceed 120 liters per hour.
