Description
Overview
The FASS STK1003 Diesel Fuel Bulkhead and Convoluted Suction Tube Kit is engineered to give your FASS Titanium Signature Series System a cleaner, higher-volume path for pulling and returning fuel inside the factory fuel module. Machined from 6061 T-6 Billet Aluminum with a Viton convoluted suction tube, this kit is built to function as both a dedicated suction point and a fuel return port, replacing the limitations of the factory setup with a design tuned for higher volume fuel systems.
Where the factory pickup tube can restrict flow, the FASS convoluted tube pulls fuel directly from inside the factory fuel basket with improved fuel volume delivery. If you have added a lift pump and upgraded your fuel line, fuel hose, and high pressure fuel line hardware, the STK1003 helps ensure the module itself is no longer the bottleneck feeding your system.
Key Benefits
Whether you run a rubber fuel hose or a braided fuel line downstream, consistent supply starts at the tank. This bulkhead and suction tube kit is designed to eliminate common tank fuel issues so your pump receives a steady, reliable draw. The 1/2 suction tube port and billet bulkhead fitting work together as a single, simple-to-install solution that serves both suction and return duties.
- Serves as both a suction tube and a fuel return port in one kit
- Machined from 6061 T-6 Billet Aluminum for a durable, precision fit
- Viton convoluted suction tube pulls fuel from inside the factory fuel basket
- 1/2 suction tube port sized to increase fuel delivery for higher-volume systems
- Unique design engineered for simple installation
- Helps eliminate tank fuel issues that can starve your system
Option & Configuration
Sold as a complete kit (Part No: STK1003) that includes the bulkhead fitting and convoluted suction tube. It is specifically suggested for installation alongside FASS Titanium Signature Series Systems, where the larger suction tube improves fuel delivery and works perfectly with higher volume fuel systems. Choose this kit when your build calls for a module-level upgrade to match your pump and fuel line hose capacity.
Fitment
The STK1003 is a universal application designed to fit Truck/SUV platforms including Ford Powerstroke, GM Duramax, and Dodge Cummins. Please note the important compatibility detail: the STK1003/1003B kit will not work on 03-04 Dodge applications. Always confirm your platform matches the intended universal fitment before installation.
For diesel owners who have already invested in quality fuel lines and want their factory fuel module to keep pace, the FASS STK1003 delivers the billet-aluminum durability and improved fuel volume needed to support a serious Titanium Signature Series build.
