FASS Titanium Series High Performance Fuel Lift Pumps for 2004 - 2005 Chevy GMC Duramax 6.6L LLY.
The FASS Titanium Series (formerly called the 95-series) is the most effective and widely used Fuel Air Separation System of its kind for light duty trucks. Each Titanium system consists of a high performance fuel supply pump, a 30k mile fuel filter and water separator. The fuel pressure and volume is far superior than the OEM fuel pump and helps protect your fuel system from potential damage, provides easier starting, smoother acceleration and a snappier throttle response. The separation of air vapor increases power and fuel economy.
