Applications
- Any diesel engine with fuel flow rates up to 60 gph
- Class 4, 5, & 6 Trucks
- Pickup Trucks
- Refrigeration Units
- Biodiesel Applications
Models and Options
- Base Model - Unheated
- Electric Pre-heater Options: 12 VDC 24 VDC or 120 VAC Overnight heater (NOTE: You canāt have both 12 VDC 24VDC and 120 VAC in this housing, only one heating option.)
- Water-In-Fuel (WIF) sensor
SEEING IS BELIEVINGĀ®
The combination of the clear cover on top, the EleMax filter cartridge and the Statapore filter media ensures better water separation, longer filter life and provides instant visual diagnostics of fuel quality to protect engine system components.
Extended Filter Life
Change the filter only when the fuel reaches the black band on the filter wrap. As the fuel rises inside the filter cover, the vapor pressure relief valve on the cap equalizes pressure and allows more of the filter media to be used.
The color of the fuel and the filter media is not an indication of when to change the filter as there is still unused media under the filter wrap.
Fuel Heating
Electric pre-heaters warm the fuel once the ignition key is turned.

Filters and Wrenches
DAVCO recommends using only EleMax filters.
Vapor relief valve and half wrap: The patented filter half-wrap and calibrated vapor pressure relief valve are integral parts of the filter assembly, ensuring maximum filter life
Filter Change Level: Change the EleMax filter element when the fuel level reaches the top of the filter
Micron Rating: Identifies the micron rating of the EleMax filter
StrataPore⢠Media: Three layers of patented laminated melt blown media inherently strips emulsified water from the fuel and increases dirt holding capacity

Tightening the collar with the wrench: Simultaneously apply downward pressure to the top of the clear cover until it is seated on the body of the Fuel Pro and hand tighten the collar until it no longer spins freely. Torque the cover assembly by rotating the collar clockwise three additional ribs using the collar wrench.
