FASS Fuel Systems Diesel System 1998.5-2004 Dodge Ram Cummins Titanium Signature Series 165GPH (TSD08165G) Part No: TSD08165G

NOTE: If the truck has been retrofitted with an in-tank System, you will need to purchase a TSD07165G Kit.

The Titanium Signature Series diesel fuel System was engineered by FASS Fuel Systems to be the top performing, longest lasting and most reliable aftermarket filtration System in the diesel industry. Rated at 165 gallons per hour and backed by a limited lifetime warranty our Titanium Signature Series System is capable of supporting your Dodge Cummins 5.9L diesel engine with enough fuel for multiple fueling upgrades.

A Titanium Signature Series System also offers advanced filtration benefits that will help protect your injection Systems, effectively extending the life of both your Bosch Injection System and Bosch Diesel Injectors. These Benefits include an improved filtration rating of 2 Microns, a built-in water separation filter and FASS Fuel Systems patented air/vapor removal process.

Aftermarket Systems are important for both daily drivers and high-performance applications when looking to improve either fuel economy or increase horsepower/torque. A common problem with Dodge Cummins 24 valve diesel engines is the failure of its factory diesel System, the System is too weak and unable to support more than stock horsepower and even over time can weaken causing a drop in fuel pressure.

This can ruin your trucks VP44 injection System, lower fuel economy and disable your truck once it stops providing fuel. The Titanium Signature Series diesel fuel Systems are the superior fuel System and filtration System, in the diesel industry.

This is because here at FASS Fuel Systems we focus on perfecting our Systems and how they are engineered, taking the extra steps that our competitors ignore while they rush to get the product out the door. By doing this we have less than a 2 percent failure rating with our motor and a design that implements unique design features you can only get with FASS Fuel Systems.

  • FASS Whisper Technology (FWT) was engineered to meet the stringent demands of today's quiet diesel engines. FASS Whisper Technology was in 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 the flow of fuel through the FASS System by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and to prevent eddy currents from forming within the corner of a 90-degree sharp angle. FASS Titanium Signature Fuel Systems are the only Fuel Air 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 back into your fuel.
  • Mass Flow Return (MFR) technology is used to continually polish your fuel by keeping a positive pressure on the fuel being delivered to the engine to prevent cavitation along with galling and scoring. Then returning the fuel, that's not yet needed, back to the tank after it has been passed through the filtration process, removing dirt, air, vapor and water. This means your fuel is being constantly Polished (cleaned), guaranteeing that your diesel truck always has the cleanest fuel possible. The MFR in combination with the optional FASS Fuel Heater options will help insure 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, 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.

1998.5-2004 Cummins 165GPH System Features:

  • New Bolt On Bracket Installation
  • Preset 16-18 PSI Fuel Pressure
  • 165 Gallons Per Hour Flow Rating
  • Removes Water, Air and Debris From Diesel Fuel
  • 2 Micron Filtration Rating

  • Improved Cold Weather Starts
  • Decreases Carbon Monoxide and Carbon Dioxide Emissions
  • 1/2 Inch Fuel Lines and Ports
  • Fuel Mileage Improvement
  • Improved Fuel Volume Delivery
  • Smoother Engine Idle
  • Optional Electric Heater Ports
  • Optional Fuel Pressure Gauge Port
  • Limited Lifetime Warranty
  • 30,000 Mile Filter Life Expectancy

It is suggested for this higher performance System to upgrade your System kit to also purchase our Bulkheading and Suction Tube kit (STK1002). Our bulkhead kit allows for a larger volume of diesel fuel to be retrieved by the fuel System and will offer a convenient return option. This is important for high-performance Dodge Cummins application that demands a large amount of diesel fuel for aggressive fueling upgrades.

NOTE: If the truck has been retrofitted with an in-tank System, you must use a suction tube kit or return this kit in its new condition for a TSD07165G Kit.

Great fog lamps boys and girls!
Color: Amber Spot Offroad Lights
Put these on my 2012 f150 market place light bar bumper and truck looks awesome and the lamps are like high beams by themselves. I can’t compliment these amber light pods enough. Intense strength. Unsurpassed brightness peeps. I bought some headlights for my 74 bronco too, can’t wait to install. Installing these pods are super easy too.

Some of the brightest yellowish green tent lights I've ever had
Color: Amber Spot Beam (ZD000706)
I put these on my 2022 Subaru outback the bottom middle section of the bumper in the front spread apart about 2 ft they are very bright they illuminate any reflective surface for at least a mile and a half to 2 mi on the interstate people just move right out of the way when you're behind them because they are so bright five stars very easy to install a top shelf

Well worth the money
Color: Amber Led Offroad Light
Got these mounted on the A-pillars on my XJ. The mounts are sturdy and fairly easy to adjust. The housings are built well. Wiring is 4 out of 5; battery connection is only a foot from the relay so I had to extend the + and - about 3ft in order to mount the relay in a good spot. Plugs seem nice but trying to run/hide the wires for the lights is difficult due to the size of the plugs. Lights are bright with excellent reach and even spread. Lens are crystal clear. We'll see how they hold up against dirt, grime, and water. Side note, the spot beam is exactly that and is not even remotely safe for on-coming traffic if it's pointed forward. I ran these off-road and they were superb and exactly what I was looking for. Well worth the price.

Not bad for money. But the spot lens is def a narrow spot
Color: 4.5inch Spot Light, Color: 4.5inch Spot Light
I did a direct comparison to BD squadron pro with spot lens. Pic one is 1 squadron spot lens, pic two is 1 auxbeam 4.5 Not a pair. Only one light each. Then the video is 2 squadron pro one with spot lenses the other with combo lens. Then both auxbeam 4.5. I wouldn’t buy the spot lens unless you have other lights or just trying to light a narrow beam a long ways. The fill light is not good. I say the brackets and the finish is on par with BD, not as deep as the XL80 but similar in size. The BD XL pro is def brighter with better fill even with spot lenses. I would say 4 of these would match the XL Pro at half the money if you have the space for four of them. But even 4 don’t match the XL80’s. But for 160 bucks it’s a good solid light.
