FASS Titanium Signature Series fuel pumps come with all the features for which FASS is known, in a compact package for a smaller profile – without sacrificing any of the power and performance you would expect in a heavy duty diesel fuel lift pump and filtration system. A FASS Titanium Signature Series pump will give you better throttle response, increased injector life and improved fuel mileage. If you own a diesel pickup truck you owe it to yourself to consider adding a FASS Titanium Signature Series fuel pump.



FASS Titanium Signature Series for light duty trucks - Some of the key benefits for light duty trucks are engine reliability, fuel savings, increased power, and the ability to safely run your truck with other power adding modifications.

FASS Titanium Signature Series for Class 8 trucks & other heavy duty applications - Generate massive fuel savings over time and increase your bottom line. Many big rig and motorhome owners see their FASS Titanium Signature Series purchase pay for itself within a few short months. Increase pulling power. Make getting on the freeway and passing easier. Increase engine reliability and minimize costly repairs. Improve fuel supply to support other power increasing modifications.

Why is a FASS Titanium Signature Series fuel air separation system and lift pump an essential modification for every diesel owner? Because your diesel runs on diesel fuel, and ensuring that your diesel-powered engine is supplied with clean fuel and is able to efficiently and properly burn the fuel is key! Dirt, water, vapor and even air all contaminate your fuel and reduce your trucks’ performance. The FASS Titanium Signature Series system removes all of these contaminants! You will see improved engine efficiency, increased injector longevity, more power and peace of mind while avoiding costly repairs.

Consider that typical No. 2 Diesel Fuel consists of about 10% air. This fuel problem is compounded by dirt and other debris that can be found in a diesel fuel tank. Without a way to filter your fuel, at some point in the future you can expect to have expensive repairs of injectors, injection pumps and other fueling components. FASS Titanium Fuel Systems address these issues head on by meticulously filtering out such problematic air & vapor — along with other contaminants in the fuel — before it’s sent to your truck’s injectors. The Titanium Signature Series diesel fuel lift pump featuring their Revolutionary Whisper Technology was engineered by FASS Fuel Systems to be the top performing, longest lasting and most reliable aftermarket filtration system in the diesel industry.

Remove Diesel Fuel Contaminants - We all know that letting dirty fuel run through your fuel system and your injectors is a bad plan. Factory filters remove many contaminants from the fuel, but they don’t do enough! With its superior 2 micron rated filter, a FASS system does a better job at removing dirt and other debris from the fuel than the factory system does. It goes a step beyond the factory system as well by removing water from the fuel. The improved removal of dirt, debris, and water reduces wear and tear on injectors and injection pumps which are costly to replace. The FASS system also separates out air from the fuel and prevents it from reaching the injectors. The result is clean fuel that can be efficiently burned.

Continuous Polishing Of The Fuel - FASS’ Mass Flow Return technology ensures that your engine always has access to the cleanest possible fuel by continually polishing the fuel. What does this really mean though? Diesel fuel goes through the filtration process to remove the contaminants and then the fuel that is needed by the engine goes to the injectors to be used, and the already filtered fuel that is not needed is returned to the tank. Fuel is constantly being moved and cleaned ensuring that the fuel that goes all the way through the fuel system to be burned is always the highest quality possible.

Increased Fuel Economy, Horsepower & Torque - One of the most important ways that a FASS fuel air separation system increases power and diesel fuel mileage is by removing the air from the fuel. In a stock diesel fuel system, larger air bubbles move through the fuel system with the fuel to the filter where the air bubbles are broken down into smaller air bubbles. The air in the fuel causes the spray from the injector tip into the cylinder to be uneven and inefficient, and also may retard the timing of the engine. Removing the air from the fuel with a FASS Titanium Signature Series system causes the fuel that is sprayed from the injector to atomize evenly across the piston. You avoid retarding your timing and end up with a longer and more efficient burn of the fuel as well as reduced emissions. More power is extracted from the fuel rather than being emitted out the tail pipe. Less fuel is wasted, saving you money. More power from each molecule of fuel makes it to the tires!

Increase Fuel Supply To Support Modifications - The FASS Titanium Signature Series lift pumps are designed with a very powerful motor. FASS has systems available to support everything from stock diesel engines all the way up to heavily modified diesel engines. Systems are available from 100 GPH (gallons per hour) for stock or mildly modified engines all the way up to 290 GPH systems able to support between 1200 to 1500 horsepower! So if you are looking for filtration, air separation, and consistent fuel delivery for a stock diesel engine, FASS has you covered! If you are needing enhanced fuel delivery for your modified work truck, play truck, sled puller or drag racing diesel truck, Class 8 Semi, diesel powered RV, farm equipment or any other diesel powered engine FASS has you covered as well!

Save Your Injectors, Save Your Engine - Here are a few ways that a FASS Titanium Signature Series lift pump can extend the life of your injectors and your engine. Having air present in the fuel reduces lubrication and also reduces the cushion that should be present between the plunger within the injector and the tip of the injector that the plunger presses the fuel through. Without this cushion provided by pure diesel fuel that is devoid of air bubbles, the plunger impacts the tip of the injector with up to 50% more force. This harsh metal on metal impact is enough force that it can crack the injector tip or even worse, break off the injector tip in the cylinder! The results can be catastrophic! This damaging effect can be accentuated on modified engines that are producing more power or are used consistently under heavy loads. Air entrained fuel also can cause a cutting torch effect as the fuel sprays into the cylinder and combustion takes place, causing the tiny holes at the tips of the injectors to be damaged. These FASS systems remove the air from the fuel!  This restores correct timing. It provides a protective cushion between the plunger within the injector and the tip of the injector. It provides an efficient spray from the injector preventing heat spots within the cylinder during combustion. It allows you to safely run under heavier loads and to safely increase your power output and support other engine modifications. At Parley’s Diesel Performance we recommend a FASS Titanium Signature Series system be used on every diesel powered engine whether it is stock or modified.

Design - (Pump, filters, brackets, etc…) The FASS Titanium Signature Series features many design benefits over competing systems on the market. Larger motors are used on the FASS systems and they have various motor sizes for the different GPH ratings of their kits. FASS kits are lower profile than the competition, so the pump and filters are more tucked up and out of the way. Performance radius cuts are utilized within the FASS pump to create the smoothest path for the fuel to flow as it leaves the filter and moves to the injectors. Compared to the competition, FASS uses heavier duty pumps, heavier duty electrical cables and connectors, heavier duty mounting hardware, tuned porting and more! All that is in addition to other technological advantages like their performance radius cuts and their industry leading water separator filter that stands head and shoulders above the competition!

No Drain Water Separator Filters - FASS water separator filters remove over 99% of the water from your fuel. Competing water separating filters that feature a drain on the bottom to drain out the water are inefficient at removing water from the fuel system! Competing filters with drains on the bottom only remove 60%-70% of the water! In addition to that, when a drain style water separator filter reaches its capacity for water removal, all water after that passes through the filter and remains in the fuel system. FASS’ extreme water separator filter uses a synthetic media and a water blocking filter. FASS’ extreme water separator filter is available in a short filter or in an XL size that has an additional 44% more capacity with the same 99%+ efficiency at removing water from your diesel fuel. Another drawback of the traditional drain style water separator filter is that as fuel flow rates increase, the water removing efficiency of the traditional filter drops. This is not the case with the FASS extreme water separator filter which maintains it’s one 90% efficiency at removing water from your diesel fuel even as flow rates increase! The FASS extreme water separator filter is simply the best water separating filter on the market!

Revolutionary Whisper Technology - After two and a half years of engineering, prototyping and testing FASS has released the quietest lift pump in the world! The FASS Titanium Signature Series features Whisper Technology. FASS was able to dramatically reduce the noise level while maintaining flow rates and their industry leading quality. You almost can’t hear these pumps running, the difference is night and day!
