Are you looking to upgrade the performance of your fuel system? Unleash the full potential of your 5.9L or 6.7L Cummins by upgrading to a FASS Fuel System. These pumps are available in multiple optimized flow rates to match everything from stock trucks to higher-demand builds. You’re looking at a premium, complete fuel system upgrade designed to replace your factory lift pump and completely transform how your diesel delivers fuel.

These systems are designed to address common Cummins fuel issues, such as inconsistent fuel pressure, air intrusion, and inadequate filtration, which can affect pump performance and long-term reliability. Whether you’re running a stock setup or have turned up the fuel, upgrading to a FASS system means cleaner fuel, more consistent pressure, and added confidence every time you get into the throttle.

IMPORTANT NOTE:
  • 1998.5-2004.5 model year trucks came from the factory with a block-mounted lift pump. Dodge has retrofitted many of these trucks with the later in-tank pumps. Before ordering, you need to determine where your current lift pump is. This can easily be done by turning the key on and listening for the pump. A faint hum from the engine bay means it is block-mounted; no sound usually indicates it is in the tank.

Which Flow Rate should you choose?

When it comes to upgrading your fuel system, choosing the right GPH (gallons per hour) rating isn’t about picking the biggest number; it’s about matching your pump to your truck’s real-world demands. A FASS aftermarket fuel system doesn’t just supply fuel, it improves filtration, removes air/vapor, and ensures your injection system gets consistent, reliable pressure. But choosing between 100, 165, 250, and 290 GPH? That’s where a lot of people get stuck.

100 GPH: Stock Reliability Upgrade (STOCK-600 HP)
  • Perfect for stock trucks or very mild setups. If you want to eliminate factory fuel issues and improve reliability without overbuilding your system, this is the ideal choice.
165 GPH: Daily Driver + Towing Sweet Spot (600-900 HP)
  • Best for trucks with mild tuning or regular towing. This is the most popular option for owners who want extra fuel capacity without going overkill.
250 GPH: Performance Builds (900-1200 HP)
  • Designed for higher horsepower setups with increased fuel demand. Ideal for trucks running upgraded injectors or pushing harder under load.
290 GPH: Maximum Fuel Delivery (1200-1500 HP)
  • Built for high-performance or future-proof builds. If you’re planning big power or want maximum fuel supply with room to grow, this is the top-tier option.

The Titanium Signature Series diesel fuel Systems are the superior fuel System and filtration System in the diesel industry. This is because at FASS Diesel Fuel Systems, they focus on perfecting their systems and engineering, taking the extra steps that the competitors ignore while rushing to get product out the door. By doing this, they have a less than 1% failure rate with the motor and a design that implements unique features you can only get with FASS Diesel Fuel Systems.

  • FASS Whispering Technology (FWT)was engineered to meet the stringent demands of today’s quiet diesel engines. FASS Whisper Technology was under development and testing for over two and a half years to meet FASS Fuel System’s high-quality and durability standards. FASS Whisper Technology effectively and drastically reduces the sound levels of the Signature Series FASS Diesel Fuel System to a “whisper” while at the same time increasing fuel flow rates. Our competition reduces noise levels by reducing flow rates.
  • Performance Radius Cuts (PRC)are an advanced machining technique used to improve fuel flow through the FASS System by creating smooth, flowing cuts in the aluminum housing. This prevents the reintroduction of air and vapor into the fuel and prevents eddy currents from forming at the corner of a 90-degree angle. FASS Titanium Signature Fuel Systems are the only Fuel Air/vapor Separation System that incorporates these exclusive Performance Radius Cuts; lesser competitors commonly use T-Bone and square 90-degree fittings that can limit fuel flow, cause restrictions, and reintroduce air/vapor back into your fuel.
  • Mass Flow Return (MFR)technology continually polishes your fuel by maintaining a positive pressure on the fuel delivered to the engine, preventing cavitation and galling/scoring, and then returning the fuel that’s not yet needed back to the tank after it's passed through the filtration process, removing dirt, air, vapor, and water. This means your fuel is constantly “Polished” (cleaned), ensuring your diesel truck always has the cleanest fuel possible. The MFR, in combination with the optional FASS Fuel Heater options, will help ensure “EXTREME” cold weather operations!
  • Bolt-On Bracket Mounts: old mounting styles required drilling or welding when mounting your new System. This has now been simplified with our new bolt-on brackets that utilize your Ford Super Duty factory bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Signature Series System takes only minutes, and all brackets are made from machined steel for superior support and strength.

Avoid These Shoes
Size: 10, Color: Grey
The pair I received (gray) was not represented well in their photos. Mine had a lime green logo which looks silly. They also bunch up very badly when you pull the laces which looks ridiculous. Cheap feeling and look bad when tied. Sending back

Great pair of shoes
Size: 10, Color: Burgundy
I was a bit concerned that these shoes would be a bit large because I normally wear a size 9 1/2 and these are a size 10. But they fit perfectly. They are very light and comfortable. 👍

Great walking shoes
Size: 11, Color: All Black
A very comfortable walking shoe that’s well made and looks like it’s going to hold up well for everyday wear. Lightweight indeed and probably doesn’t require much cleaning. Easy to get on and off without much stress though.
