FASS Universal Heavy Duty Drop-In Series Fuel System

Remove the entrained air and vapor from your diesel fuel and a chain reaction follows. Tap any feature to see each link in it.

At least a 10% gain in fuel lubricity under stationary conditions — and that’s the floor. Agitation begins the moment the engine does, and vehicle motion compounds it. Restricting filters, higher elevation, heated fuel, and lower fuel levels drive air/vapor higher yet. The field calls it “fuel starvation.” Physics calls it entrained air/vapor. Strip it out, and lubricity gains travel well north of 10%.

FASS will “TRIPLE” the life of your fuel injection system — and keep thousands of dollars in your pocket over the long haul.
