Beans Diesel Bean Machine Micro Sump (280032)

Small footprint. Big performance.

The Beans Machine Micro Sump is the compact, budget-friendly version of Beans Diesel’s proven fuel tank sump design. Precision-machined from solid 6061 billet aluminum, it delivers reliable fuel delivery for aftermarket lift pumps without the size or cost of a full-size sump.

It installs in about 5 minutes with no tank drop. Drill a single 1-1/2" hole, slide the internal Pacman backer ring through the opening, and tighten one stainless steel bolt. The O-ring seal provides a leak-free connection with fewer potential leak points than multi-bolt designs.

The sump draws fuel from the bottom of the tank so you can use virtually every drop without sucking air or starving the system below 1/4 tank. An integrated standpipe helps reduce sediment reaching your filters. It works as a fuel feed or return, making it a versatile match for high-flow systems like AirDog and FASS.
