The Titanium Signature Series 250GPH Lift Pump is a great upgrade for your 6.6L Duramax engine. Unlike other diesels, the Duramax lacks a factory lift pump. This makes the CP3/CP4 injection pump pull fuel under a vacuum, adding stress and risking air in the fuel. That's where the Titanium FASS Fuel Pump steps in.

Engineered by FASS Diesel Fuel Systems, the Titanium Signature Series diesel fuel System is the best - performing, longest - lasting, quietest, and most reliable aftermarket filtration System in the diesel industry. With a 250 - gallon - per - hour rating and a limited lifetime warranty, it can supply enough fuel for 900 - 1200 HP for your GM Duramax 6.6L diesel engine. It also offers advanced filtration, protecting the injection System and extending the life of injectors. Benefits include 2 - micron filtration, a water separation filter, and a patented air/vapor removal process. It helps solve common injector failure issues in Duramax engines.

This kit includes a Bulkhead Fitting and Suction Tube. Made from 6061 T - 6 Billet Aluminum, the Bulkhead fitting serves as both suction and return, with a 5/8” Suction Tube, suction fuel line, and a ½” Fuel Return Port. The new version simplifies installation by allowing direct plumbing of the return line, eliminating filler neck cutting. The PTFE Teflon pickup tube can be easily cut for different fuel tank depths. You can safely operate down to about 1/8 tank of fuel when properly installed.

FASS has perfected its System, with a motor failure rate of less than 2% and unique design features.

Additional Info

FASS Whisper Technology (FWT) meets the demands of quiet diesel engines. After over two and a half years of development and testing, it reduces sound levels to a “whisper” while increasing fuel flow, unlike competitors who cut flow to reduce noise.

The FASS Fuel Systems are great for both daily drivers and high - performance applications. Added filtration and air/vapor removal enhance the fuel injection system's life and improve engine performance, including horsepower, idle quality, throttle response, fuel economy, and cold - weather operation with fuel heating options.

Performance Radius Cuts (PRC) improve fuel flow in the FASS System. They prevent air and vapor re - entry and eddy currents. FASS Titanium Signature Fuel Systems are the only ones with these cuts, while competitors' fittings can limit flow and re - introduce air.

Using your Titanium Signature Series 250GPH Lift Pump is straightforward. First, make sure to follow the installation guide carefully. The new bolt - on bracket makes it easy to install. Connect the suction and return lines as described in the instructions. The 5/8” suction tube and ½” fuel return port are designed for a proper fit. Once installed, your pump will start supplying fuel to your engine. Remember, this pump is designed to support engines with a power rating of 900 - 1200HP, so it's a great match for your 2001 - 2016 GM Duramax 6.6L engine. When it comes to maintenance, the filter has a life expectancy of 30,000 miles. Check the filter regularly and replace it when needed. The FASS Whisper Technology keeps the pump quiet, but if you notice any unusual noises, it could be a sign of a problem. Make sure the fuel you use is clean to avoid debris clogging the system. Also, the PTFE Teflon pickup tube can be cut to fit different fuel tank depths, but ensure it's properly installed so you can safely operate down to about 1/8 tank of fuel. With its limited lifetime warranty, you can have peace of mind knowing your pump is built to last.
