ZHSYMX Fuel Tank Sump Kit with Integrated Return for Diesel Trucks (AirDog/FASS) – 3" Hole Saw Included

Overview

The ZHSYMX Fuel Tank Sump Kit is a purpose-built upgrade for diesel trucks that use AirDog or FASS pumps. This kit adds a built-in fuel return and a stand pipe that clearly separates return fuel from feed, helping to keep the fuel path organized while you work. The result is a cleaner, more streamlined installation that doesn’t require a tank drop, saving time and reducing mess in the service bay or garage.

Why this setup matters

In practical terms, a thoughtfully integrated return path can simplify routing and maintenance. The components are designed to work with both stock and aftermarket tanks, and the body is constructed from aircraft-grade T6 billet aluminum for a sturdy, long-lasting feel. By avoiding a drop-in installation, you may experience a smoother workflow and a more contained fuel area during upgrades or routine service.
