Discontinued - See Titanium Series
Universal - Many Makes & Models
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.
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.
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.
All Class 8 FASS systems all require fuel line kits for installation. Please see related products for Fuel Line Kits.
