FASS - Heavy Duty Series

The FASS Heavy Duty Series (formerly the 150 Series) is a high quality fuel supply pump with far superior reliability, fuel flow and fuel pressure characteristics than that of the factory fuel supply pump. FASS Heavy Duty Series systems have the patented ability to remove air/vapor from diesel fuel that will increase power and fuel mileage, and will also extend the life of your fuel injection system. The fuel filter and water separator also provides additional protection from dirt and water contamination.

Heavy Duty - VS - Titanium - VS - Platinum
The performance specifications between the Heavy Duty, Titanium and Platinum series kits are all very similar. The primary difference is in the filters and the overall size of each system.

• Heavy Duty Series - 14" height
• Titanium Series - 12-1/8" height
• Platinum Series - 9.5" height

Heavy Duty series filters are rated at 40k miles, and the Titanium series filters are rated at 30k miles. Because of their larger size, the Heavy Duty series kits are more commonly used for heavy duty trucks or race/competition vehicles. Titanium series kits are usually a better choice for most light duty trucks. Platinum series kits are also great for most light duty trucks where mounting space is limited.
