Fuel Cell 4gal Upright w/sump Aircraft Fill

The RJS Safety Fuel Cell 4-gallon Upright with Sump and Aircraft Fill is a purpose-built fuel cell engineered for drag racing and high-performance motorsports applications. This 4-gallon fuel cell combines a compact footprint with robust construction, featuring an upright design that maximizes packaging efficiency in tight engine bays while maintaining structural integrity under the extreme vibration and acceleration loads encountered in competitive racing environments.

Measuring 9.13 inches wide by 9.13 inches deep by 16.13 inches tall and weighing just 6 pounds, this fuel cell delivers a low-profile solution for weight-conscious builds. The cell features two 8 AN male outlets for fuel delivery and a 6 AN male vent line, allowing dual fuel distribution or pressure/return configurations depending on fuel system architecture. The aircraft fill cap design provides convenient refueling access and pressure sealing. Interior construction includes alcohol foam to suppress fuel sloshing and foam separation during hard cornering, acceleration, and deceleration—critical for maintaining consistent fuel delivery during competition runs. The polycarbonate plastic construction resists impact and vibration fatigue while remaining lightweight.

This fuel cell is designed for dedicated drag racing competitors, bracket racers, and high-performance street cars requiring a compact, reliable fuel storage solution that performs under sustained high-load conditions. The upright orientation fits within constrained engine compartments common to modified vehicles, while the sump design ensures fuel pickup remains consistent even under g-load and vehicle attitude changes. RJS Safety fuel cells are engineered to meet demands that stock fuel tanks cannot withstand in competitive motorsports.

For racers and tuners selecting a fuel cell, capacity, outlet configuration, and construction material directly impact fuel system reliability and vehicle performance. The 4-gallon capacity suits bracket racing, short-course competition, and performance vehicles where weight minimization is prioritized over extended cruising range. The dual 8 AN outlets enable flexible fuel system design, supporting both traditional single-feed and modern dual-feed fuel injection systems.

SKU 3000301 is the direct part identifier for this RJS Safety fuel cell. Verify outlet sizing and thread type against your existing fuel line adapters before ordering to ensure seamless integration into your fuel system.
