FASS Ultimate Industrial Fuel System Upgrade: For Caterpillar C10, C11, C12, C13 (& ACERT) Engines

The FASS integrated fuel pump makes priming effortless. Turn the key ON, give it a moment to prime, and fire it up, typically in under 1 minute.

FACT: With FASS, the GPH number is the flow rate on diesel fuel.

Dependability + simple and straightforward = PRODUCTIVITY!

That extends the life of our proven 20,000+hr/1,000,000+ mile motor and adds a clean, upgraded appearance to the system — pushing FASS closer to a 0% failure rate. “Striving for Perfection, Settling for Excellence.”

FASS delivers exactly what we state: the flow rate and the pressure your application needs, in our part number. Others slow the flow to quiet the motor and market an “assumed” GPH number that falls short of what you thought you bought.

The FASS Ultimate Fuel System will “TRIPLE” the life of your fuel injection system - and keep thousands of dollars in your pocket over the long haul.

From the field - FASS optimizes fuel efficiency, with customers consistently reporting gains of 9-11%, coupled with horsepower gains. Semi operators consistently report pulling one full gear (two splits) higher on grades.

Customers hear it first, then feel it - in the mirrors, in the steering wheel. The engine runs smoother, and less vibration reaches the cab. Less vibration means less stress, and less stress means a longer life.

CATERPILLAR rated your engine in a “Test Cell” - clean, non-agitated fuel, positive flow, roughly 10% air in solution. FASS delivers those same conditions in the “Real World” with the air removed, edging performance just past the “Test Cell” rating.

The Industrial Series PLUS delivers virtually pure fuel under pressure to the engine’s OEM fuel delivery/injection pump. Even so, the turbulence inside that pump pulls vapor back out of suspension - a small amount, but enough to matter. The Drop-In Fuel System (DIFS) removes it, adding one final layer of protection before combustion.

Every one of these benefits leads to the same place: COST. FASS reduces maintenance spending across the board, and while that may sound too good to be true, the physics and the customer reports say otherwise.

• Soot/Emissions: down 18-76.8% - plus reductions across CO, CO₂ and oxides of nitrogen.
• EGTs (turbo temps): typical stock applications 50-100°F; modified applications 150-200°F+, and more in severe situations.
• 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.
• Replace filters and service fuel with FASS filters - that’s it.
• Vehicle stays working.

To match a cellulose filter to the capability/efficiency of a microglass element you will need a filter four times the size of filter. Our filter has four times the effective filtration, and catches finer debris along the way.

Better flow, less motor noise, less cavitation and a filter you can service. Cellulose restricts flow by design, and restricted flow means a louder, harder-working motor and pump.

Pick the right package and forget about gelling issues.

"I “DROVE” a truck to Tuktoyaktuk - the Arctic Ocean, Northwest Territories, Canada - operating on straight untreated #2 fuel from Mississippi. Parked it outside overnight at -35°F, turned the heaters on from my hotel room with the FASS Connect……it started like it was summer." ~ Brad Ekstam, Founder & President of FASS

Fuel the engine doesn't consume cycles back through the filters, getting progressively more "Polished" until it's required by the engine.
