🛠️ G&R Billet Aluminum Bottom Sump with Integrated Fuel Return – Fast Install, Leak-Free, High-Flow
Simplify your diesel fuel system upgrade with the G&R Billet Aluminum Bottom Sump featuring an Integrated Fuel Return. This innovative design eliminates the need to route your return line to the top of the tank or cut into the filler neck—cutting install time from hours to minutes.
Machined from T6061 aircraft-grade billet aluminum, this sump uses a clamp-in o-ring seal—stronger and cleaner than “ring of bolts” styles. The -8 AN O-ring outlet supports high-volume fuel flow, while the built-in -4 AN drain lets you empty your tank fast if needed.
