By ensuring your engine is fed clean, consistent fuel you will gain power, fuel economy, and reliability. FASS is a proven name in diesel fuel lift pumps that not only deliver the fuel, but also clean the fuel down to 3 microns as well as remove entrained air.

The Titanium Signature Series diesel fuel lift pump 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 five year, one million mile warranty, the Titanium Series lift pump is capable of supporting a semi diesel engine with enough fuel with stock fueling system upgrades. A Titanium Series lift pump also offers advanced filtration benefits that will help protect the injection systems, effectively extending the life of your injectors. These benefits include an improved filtration rating of 3 Microns, a built in water separation filter, and FASS Fuel Systems patented air/vapor removal process.

The Titanium Series diesel fuel pumps are the superior fuel pump and filtration system in the diesel industry. This is because FASS has a sharp focus on perfecting their pumps and how they are engineered, taking the extra steps that competitors ignore while they rush to get product out the door. By doing this, FASS has less than a 2% failure rate and a design that implements unique design features you can only get with FASS Fuel Systems.

  • FASS Silencing Technology (FST) was developed by the engineering team at FASS Fuel Systems to help reduce the noise created by aftermarket fuel and air separation diesel lift pumps. By using radius cuts, tighter tolerances on all gears and a high quality military Spec'd Coating over the aluminum base, FASS Fuel Systems was able to develop the quietest fuel air separation system on the market.
  • Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the diesel lift pump by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and also to prevent stagnate fuel pockets from forming within the corner of a 90 degree bend. FASS Fuel Systems Titanium Series Diesel Fuel Pumps 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 and 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 moved and cleaned, guarantying that your diesel truck always has the freshest and cleanest fuel possible.
IMPORTANT NOTES:
  • The vast majority of unmodified Class 8 semi trucks will operate perfectly with our 165gph (T 165G model). Modified vehicles may require the higher flow rate of our T 250G model. Other specific fuel rates are also available.
  • Class 8 semi trucks with Unit Injected Mechanical (UIM) fuel systems require an additional oil pressure switch (part number 78143) which is included in this kit for proper operation.
  • Class 8 FASS systems all require fuel line kits for installation. Please visit our Fuel Line Kits page for fitment options.

Female with no knowledge about cars seal of approval!
Size: For Mazda 3 14-18 2.0L/2.5L|Mazda 6 14-21 2.5L
Perfect for my 2016 Mazda3. I am a young female with zero tools and zero knowledge about cars. My dealer was asking over $60 to change these out, and after a 5-minute course at YouTube University, I was able to do everything myself in under 15 minutes. It’s my crowning achievement of 2026. I recommend gloves when you go to change out the engine and make sure it’s wiped out and cleaned before you put the new one in! But other than that, it’s honestly just popping a few things out, changing the filters, and then popping them back into place. They look almost identical to the filters that were already in there. There was no wrestling with making them fit because they just slid easily into place. Great buy and unbeatable price if you have a few minutes to spare to do it yourself!

Easy Install - Looks like the Original
Size: For Ascent 19-26|Crosstrek 2.0L 18-22/2.5L 21-22
Both of these filters, cabin and engine are really easy to install at home with NO tools needed and at a fraction of the price that dealers charge. These filters are for a Subaru Impreza and look almost identical to the originals and fit perfectly. Cabin filter installation is by dropping the glove box - detach damper rod and unclip sides. Unclip filter cover behind glove box and remove/replace filter checking airflow direction is the same as the old filter. Reinsert glove box and push up to locate side clips. Re-affix damper rod and you're done. Engine filter is equally easy. Unclip air filter housing (not necessary to remove entirely) slide out old filter and insert new on in same orientation. Re-attach clips and done. Took me 10 minutes to change both filters. Longest part was emptying all the cr*p out of my glove box. Good quality filter, easy to install and saves time and money. I bought a second set for a Mazda CX-5 non turbo and quality was the same. Installation exactly the same as above for the Subaru

Never Pay Again. Easy and affordable for your health and the vehicle.
Size: For Sonata Gas 2015-2019
Way easier to replace than I thought. I’ve done a cabin filter before, but never the engine air filter. After this, I’ll never pay someone to do it again. I actually went into a store first, and the cabin filter alone was the same price as this set that includes both the cabin and engine filters. Since I needed both, this was a no-brainer. Install was quick and straightforward, even for someone who’s not a "car guy". I can’t speak scientifically on how well they filter, but they’re definitely better than the mouse-destroyed ones that were in this car before. Huge improvement. Highly recommend if you’re looking to save money and do it yourself. They fit well and seemed to be exactly what was needed and expected.
