FASS Fuel Sump Kit SK5501

Upgrade your fuel system with the FASS Fuel Sump Kit SK5501 for most diesel applications. This kit improves fuel delivery, simplifies installation, and helps eliminate common fuel supply issues.

Improved Fuel Delivery at the Source

The FASS Fuel Sump Kit SK5501 places the suction port at the lowest point of the fuel tank. Because of this, it allows fuel to flow more consistently to your system.

As a result, your truck maintains steady fuel supply under load. In addition, it helps prevent starvation issues during acceleration or braking.

Eliminates Common Fuel Supply Problems

Many trucks experience fuel supply issues near a quarter tank. However, this sump kit solves that problem by pulling fuel directly from the bottom of the tank.

Because of this design, you get consistent fuel delivery even at low fuel levels. This improves reliability and overall system performance.

Simple Installation with No Tank Drop

This kit requires only a single hole to be drilled into the fuel tank. Because of this, you can complete installation without dropping the tank.

In addition, the single bolt design simplifies the process. So, you save time while still getting a secure and effective installation.

Built for Performance and Durability

FASS builds this sump kit from 6061 billet aluminum. Because of this, it offers excellent strength and long-term durability.

The extra-large fuel bowl acts as a reservoir. As a result, it maintains consistent fuel supply even during aggressive driving conditions.

Designed for Return Style Systems

The FASS Fuel Sump Kit SK5501 includes both a 1/2” NPT suction port and a 1/2” NPT return port. Because of this, it works seamlessly with return-style fuel systems.

It is also ideal for use with FASS Titanium Signature Series Systems. This combination improves fuel delivery for higher volume setups.
