Description
Overview
The FASS STK1005 Diesel Fuel Bulkhead and Viton Suction Tube Kit is engineered to mount directly to your fuel tank module and unlock the full potential of your FASS Titanium Signature Series system. By upgrading the factory suction path with a purpose-built bulkhead fitting and a durable Viton convoluted suction tube, this kit delivers improved fuel volume to your pump so your diesel gets the steady, reliable feed it demands.
Because the larger suction tube draws fuel directly from the fuel basket, you can run your truck below 1/8 tank of fuel safely — eliminating the frustrating 1/4-tank fuel starvation issues that plague many diesel platforms. It’s a smart, foundational upgrade for anyone serious about consistent fuel delivery.
Key Benefits
This bulkhead and convoluted suction tube combination is designed around a dedicated FASS suction port that increases fuel delivery while keeping installation simple. The unique design makes it a straightforward addition to your existing setup, and it works perfectly alongside higher-volume fuel systems where the extra suction capacity truly pays off.

Configuration & Installation
Sold as a complete kit, the STK1005 can be installed on its own or set up as a pair to create a high-flow suction and high-flow FASS return arrangement.

The larger suction tube is specifically matched to improve fuel delivery for higher-volume applications.

The FASS STK1005 is a Titanium Signature Series accessory intended for universal diesel applications, covering Ford Powerstroke, GM Duramax, and Dodge Cummins trucks and SUVs. It is suggested to be installed together with FASS Titanium Signature Series Systems, where its improved suction and volume capabilities are put to full use.
