Platinum Series

FASS Platinum Series Diesel Fuel Supply Pump

You can expect the same high quality systems that FASS is known for at a lower cost. FASS came up with a new product using their technology and quality to design a smaller version of the fuel air separation systems. A completely new base for the system was used in order to keep size to a minimum. The fuel filter and water filter are now combined and still maintains the quality air separation.  The Platinum Series was designed for the light truck applications in mind.  Applications for this series include Dodge, Ford and Chevy.  The Platinum will cover stock to moderate performance applications.


Titanium Series

 FASS Titanium Series Fuel System

The Titanium Series is designed for the pickup while utilizing all the best features of the HD series. Built in a smaller compact version, the Titanium Series offers flow rates up to 260gph. This size difference allows you to tuck the pump closer to the frame for better clearance and less visibility, without sacrificing any features of FASS systems. The same motor used on the HD Series (class 8 applications) is also used on the Titanium Series.  The high performance in a small package makes the Titanium our pick for stock to competition pickup trucks.


Heavy Duty Series

 FASS Heavy Duty Series Diesel Performance Fuel Supply Pumps

As of March 1st, 2013 the FASS HD Series will no longer be available for the Pick-up Truck Market. Improvements to the Titanium Series now gives you the capability to reach flow rates up to 260 gallons per hour which previously could only be achieved with the HD Series.  With these improvements the Titanium Series is now the premier Fuel Air Separation System for the daily driver and competition applications!  Not only can the Titanium now achieve flow rates up to 260gph but its smaller compact design makes it the ideal model for Pick-up Truck applications.

The Heavy Duty Series is still available but moving forward will only be available for the Class 8 Market.  The large filter capacity makes this pump the leader in the Class 8 market, where long stays on the road and high volume is required.  The HD series provides strength and reliability you can count on even in the most extreme conditions. 


Adjustable Pump Only Systems

 FASS Adjustable Pump Only Series Diesel Performance Fuel Supply Pumps


The “FA” series from FASS is the most versatile High Performance Fuel Pump (pump only) on the market. The FA's allow the customer to tweak the fuel pressure with a simple adjustment that can be done while it is running. The Boost Compensation Port can be used to increase the pump pressure as the engine boost levels climb.  This will result in more consistent fuel pressure as the fuel required by the engine increases. These pumps can be plumbed into the ports on the filter systems and set to kick in when the high demand is necessary which results in a perfect street/strip setup!  Flow rates are available from 90 – 260gph and fuel pressure from 0 – 100psi!. The FA’s will work well from stock, all the way to extreme performance applications!


GM Duramax Flow Enhancer Fuel Pump

 FASS GM Duramax Flow Enhancer Fuel Pump

After having great success with the Dodge Direct Replacement Pumps (DDRP), the Dura-Max Flow Enhancer was created and is now available for the GM Duramax equipped engines. GM Duramax trucks do not have a stock lift pump which forces the injection pump to "pull" the fuel all the way from the tank, creating a vacuum and constantly introduces more air and vapor into your fuel. The Duramax Flow Enhancer creates a positive flow of fuel, "pushing" it to your injection pump, eliminating vacuum and drastically reducing air and vapor in your fuel. This is an excellent lower cost alternative to the other FASS fuel systems. This is recommended for stock power levels.
