Upgrade your 2015 - 2016 Duramax engine significantly! The factory - built Duramax engine lacks a lift pump. Instead, the CP4 injection pump pulls fuel under vacuum, causing unnecessary wear. The FASS pump solves this problem, fueling your engine properly and efficiently.
A Titanium Signature Series System offers advanced filtration. It protects your Duramax’s injection systems, extends the life of injectors, and has a 2 - micron filtration rating, a built - in water separation filter, and a patented air/vapor removal process.
FASS perfected this system before market release. It has a less than 2% motor failure rate and unique design features only available with Fass Diesel Fuel Systems.

Additional Info
FASS Whisper Technology (FWT) was developed for over two and a half years to meet high - quality standards. It reduces the sound of the Signature Series to a “whisper” while increasing fuel flow, unlike competitors that reduce flow to cut noise.
Mass Flow Return (MFR) technology polishes your fuel. It maintains positive pressure to prevent cavitation, then returns unneeded fuel to the tank after filtration. Combined with optional fuel heaters, it ensures cold - weather operation.
Performance Radius Cuts (PRC) are advanced machining that improves fuel flow in the FASS System. It prevents air and vapor re - entry and eddy currents. FASS Titanium Signature Fuel Systems are the only ones with these cuts, unlike competitors with fittings that can limit flow.
On Bracket Mounts simplify installation. No more drilling or welding. Just use the factory bed bolt. All brackets are machined steel for strength.
