Transfer Flow fuel systems are designed to work only with specific 

components which have been selected for their unique properties. Years of 

design work have produced the finest auxiliary fuel system available that relies 

on relatively few, but critical parts. The components used in Transfer Flow fuel 

systems are not generic or “off the shelf” parts and cannot be replaced with 

parts that appear to be similar. 

For example, the in-line fuel pump used with our TRAX 3™ system appears to 

be a normal fuel pump, but it is actually a high-quality solenoid pump with a 

critical forward and reverse check feature. 

Under no condition should any 

other pump be substituted for the provided pump.

This auxiliary fuel system has been outfitted with a replaceable fuel filter 

that requires periodic service. The filter is available though automotive parts 

retailers and is not covered by Transfer Flow’s warranty. The filter should be 

inspected/replaced every 3–6 months depending on the conditions that the 

vehicle is operated in and the quality of fuel purchased. Transfer Flow will not 

honor warranty claims from diagnosis or replacement of obstructed filters.
