HD Series

Fuel Air Separation Systems


The HD Series is the mother of all FASS pumps. The large filter capacity makes this pump the leader in the Class 8 market, where long stays on the road and high volume (up to 260gph) is required. Designed to set the standards in the Class 8 market, the HD series provides strength and reliability you can count on even in the most extreme conditions.

* NOTE The vast majority of unmodified Class 8 semi trucks will operate perfectly with our 150gph HD 150G model. Modified vehicles may require the higher flow rates of our HD 220G or our HD 260G models. Other specific fuel rates are also available. Contact us for more information.

* NOTE Class 8 semi trucks with stock Caterpillar C16 or stock Cummins ISX Signature 600 engines will require the 220gph flow rate of our HD 220G model.

* NOTE Class 8 semi trucks with Unit Injected Mechanical (UIM) fuel systems require an additional oil pressure switch (part number 78143) which is included in all of our HD UIM Kits for proper operation. The 78143 is listed on our Miscellaneous Accessories page also.

* NOTE Class 8 FASS systems all require fuel line kits for installation. Please visit our Fuel Line Kits page for fitment options.
