Features

• Remove the entrained air and vapor from your diesel fuel and a chain reaction follows. Tap any feature to see each link in it.
• FASS will “TRIPLE” the life of your fuel injection system — and keep thousands of dollars in your pocket over the long haul
• Customers consistently reporting gains of 6-11%, coupled with horsepower gains.
• Truck Only: 1 – 2.5mpg increase
• Loaded: .5 – 1.5mpg increase
• Diesel engine output depends on precise fuel injection timing, and air/vapor undermines that precision
• Soot/Emissions: down 18-76.8% — plus reductions across CO, CO₂, and Oxides of Nitrogen.
• Regens: Many customers report their regen frequency drops by about half.
• EGT’s (Turbo Temps): typical stock applications 50-100°F; modified applications 150°F and up, over 200°F.
• Water/Oil Temps: reported 15-25°F.
• Oil Consumption: customers have reported reduced oil consumption.
• The benefit, simply put: competitors’ filters fill with water, pass that water to the fuel injection system, and you’re looking at catastrophic damage and downtime
• Repair or replace the fuel system — are the parts even available?
• Replace filters and replace fuel — more shop time, more cost.
• Vehicle sits idle, producing nothing — and where are you, loaded or on vacation?
• No fuel system repair or replacement.
