FASS technology separates entrained air and fuel vapor from the diesel fuel while filtering particulate contamination and separating water.\u003c\/p\u003e\n\n\u003cp\u003eRemoving air and vapor from the fuel can help provide more consistent fuel delivery and improve fuel lubricity. FASS states that its air\/vapor separation technology can improve fuel lubricity by at least 10% and is designed to help protect injectors and other high-pressure fuel-system components.\u003c\/p\u003e\n\n\u003cp\u003eThe system also uses \u003cstrong\u003eMass Flow Return (MFR)\u003c\/strong\u003e, which returns unused fuel through the filtration system rather than sending it directly back to the fuel tank. This allows the fuel in the tank to continue being filtered as the system operates.\u003c\/p\u003e\n\n\u003ch2\u003eHeavy-Duty Diesel Applications\u003c\/h2\u003e\n\n\u003cp\u003eThe DIFSHD3001 is a universal heavy-duty system intended for commercial diesel applications.
