No matter how carefully gasoline or diesel is handled, contamination in the form of dirt, sludge or water will always find its way into your fuel tank. With modern engines now injecting fuel at over 36,000 psi (2,500 bar) and injector tolerances measured in microns, even a small amount of dirt or water corrosion can cause damaged components, reduced engine efficiency, and in severe cases, complete injector break-down.

Racor Spin-on Series Fuel Filter Water Separators provide maximum protection of modern diesel and gasoline engines by effectively removing contaminants from fuel, such as water, silica, sand, dirt, and rust. The mounting head and filter body are protected with a durable electrostatically-applied powder coating for superior corrosion resistance. The unique spin-on filter design is easy to service and features a reusable clear plastic or metal contaminant collection bowl with a self-venting drain or metal plug.

An integral priming pump is available as an option for diesel filter models; but they are not recommended for gasoline models. The pump allows for easy priming and simplified service by eliminating messy filter pre-filling and engine hard starting. Diesel models are also available with optional fuel heaters to ensure performance in extremely cold environments.

All Spin-on Series Fuel Filter Water Separators utilize Racor’s high-efficiency Aquabloc® engineered media, which repels water and removes solid contaminants from fuel at 98% efficiency of their micron rating. To meet the unique requirements of customers’ engines, three different micron ratings are available for purchase, including:

30 micron (98%@30 micron) – Ideally suited as a pre-filter to protect downstream filters from excessive contamination. Extends the life of on-engine filters.

10 micron (98%@10 micron) - Captures more contaminants than 30 micron elements, and is more effective at stopping water. Extends the life of the entire fuel system.

“2” micron (98%@4 microns) – Provides maximum water removal and filtration and is capable of protecting all modern injection systems, while greatly extending the life of difficult-to-service on-engine filters.

How it works:

Racor Spin-on Series Fuel Filter Water Separators use Aquabloc® media to reliably remove dirt and water from diesel and gasoline. Aquabloc® media is pleated, corrugated, and designed for high water rejection and long service life. Fuel entering the filter head is diverted downward past the vertical media pleats, allowing larger water droplets and contamination particles to fall directly to the collection bowl. Smaller water droplets converge and coalesce on the specially treated media surface until they are large enough to also drop to the collection bowl. Small contamination particles are stopped at the surface of the Aquabloc® media, while even smaller particles are held deeper in its layers. This results in dry, clean motor fuel being delivered to your engine.

Notes on use:

• Hand priming pumps are not recommended for gasoline applications.
• Gasoline filters used in an enclosed location should use a metal bowl.
• Clear bowls in gasoline systems are a routine inspection item: Inspect for damage, deformation, and discoloration often, and replace as necessary.
• Heaters and water probes must NOT be used in gasoline

Notes on selection:

To ensure selection of the proper Spin-on Series filter, follow the steps below:

1.Choose mounting type (one small filter model is available as an in-line unit).

2.Choose “cold weather” heater type or none. Electric heaters are for heating static fuel as a starting aid and may not supply enough fuel flow for full-load operation. Filters with coolant heaters can heat and supply fuel at full flow for full-load engine operation. Heaters are NOT to be used in gasoline applications.

3.Select total flow rate th
