Meets/Exceeds 2017 engine manu­facturer’s stringent water separation
requirements

HOW IT WORKS

Models and Options

• Base Model - Unheated

• Electric Pre-Heaters

• 12VDC, 24VDC Pre-heater

• Water-In-Fuel (WIF) Sensor

• Fuel from the tank enters the DieselPro body (suction side of the fuel system).

• Large contaminants and “free” water are separated from the fuel and remain in the body.

• Fuel rises into the clear cover.

• Contaminants and emulsified water are captured by the filter media.

• Fuel level continues to rise to maintain a fuel path through the clean filter media with low restriction.

• Clean, water-free fuel exits the DieselPro and flows to the engine fuel injection system.

See when NOT to change the fuel filter.

See the condition of the fuel. Seeing what collects on the filter media or what’s happening inside the clear cover can help

diagnose many fuel and mechanical conditions.

“Filter on Top” configuration. Water and debris removed from the fuel falls to the lower chamber and stays away from the
filter media resulting in longer filter life.

Built in protection when priming the fuel filter. Unfiltered fuel is kept on the “dirty” side of the filter media during priming
ensuring only clean fuel reaches the engine.

When new, the fuel level in the filter will be very low with
minimal restriction. As the filter is used, contaminants

collect on the filter from the bottom up. Fuel rises on the
filter indicating remaining filter life.

Fuel level at filter wrap level. Even though the fuel level
is now more than half of the filter element, the fuel is still
flowing through clean media at minimal restriction levels.
The filter still has significant life remaining.

Fuel level increases in clear cover. As contaminants
collect on the filter, the fuel rises to a non-contaminated
section of the filter, providing optimal filtration while main­taining lowest restriction.

The filter element is now completely covered by fuel.
At this point, all of the media’s surface area is utilized.
Restriction is increasing and the filter element should be
changed at the next scheduled maintenance interval.

E IMPORTANT SAFETY PRECAUTIONS

General Safety Precautions

• FOR USE WITH DIESEL FUEL ONLY

• To avoid serious injury or death, follow the safety information in this document.

• Keep this manual. If you need to replace the manual, call customer service at 800-328-2611
or visit www.davco.com for a replacement.

• Refer to appropriate regulations for environmental and workplace safety rules.

WARNING: To prevent personal injury

• Scalding hazard: When diesel fuel is circulated through an operating engine, it can become very hot. Do not allow
fuel to come in contact with eyes or unprotected skin. Allow the engine and fuel to cool to ambient temperature
before replacing the fuel filter or performing service operations which could result in spillage of fuel from the fuel
system.

• Fire Prevention: Heated fuel can form combustible vapor mixtures in the area around the fuel source. To eliminate
the potential for fire, keep open flames, sparks or other potential ignition sources away from the work area. Do not
smoke during filter replacement or service operations.

• Inhalation Precaution: Always perform engine or vehicle fuel system maintenance in a well ventilated area that is
kept free of bystanders.

• The ignition key must be in the off position, unless otherwise directed. To avoid unintentional engine startup, use a
lockout key and/or signage to alert personnel that work is being performed.

• Do not energize the pre-heater outside of the Diesel Pro. It can become very hot.

Government Regulations

• Engine fluids (oil, fuel, and coolant) may be a hazard to human health and the environment. Handle all fluids and other
contaminated materials (such as filters and rags) in accordance with applicable regulations. Recycle or dispose of
engine fluids, filters, and other contaminated materials according to applicable regulations.
