Fuel System Logic
SYSTEM TYPE
Direct Replacement (OEM Integrated)
Heavy-duty high-capacity replacement tank precision-engineered for the 2022+ RAM 1500 TRX (6.2L Supercharged HEMI V8). Custom-contoured to maximize underbody fuel storage without compromising suspension travel or off-road ground clearance, it upgrades capacity from the 125L (33 Gal) OEM tank to a massive 186L (49.1 Gal). It seamlessly integrates with RAM’s factory fuel sender, high-flow pump, and EVAP emissions system for a 100% codes-free, high-performance overland upgrade.
Gauge Behavior: The factory fuel gauge remains fully functional, scaling smoothly across the expanded 186L capacity. Due to the upgraded volume, the gauge needle will dwell longer at the "Full" position and decline more gradually than stock. When the low-fuel warning triggers, a physical reserve of approx. 22L remains in the tank. Distance to Empty (DTE) is dynamically calculated by RAM's ECU based on real-time consumption, providing a dependable 80km - 110km+ safety margin.
Structure & Protection Design
01
02
Internal Baffle System
Internal baffles help control fuel movement inside the tank, improving vehicle stability and fuel pickup reliability on uneven terrain.
03
Heat Shield Protection
Integrated heat shielding reduces exhaust heat exposure and helps protect fuel system components from excessive temperature.
04
Strap Shield Protection System
Recessed mounting pockets allow the tank straps to sit flush within protected zones, reducing the risk of strap damage or snagging when sliding over obstacles off-road.
05
Quick-Connect Fuel Line Fittings
Equipped with OEM-style quick-connect fittings for secure sealing, simplified installation, and reliable fuel line connections.
06
Integrated Drain Port
An integrated drain port allows fuel to be safely drained for maintenance, repairs, or long-term storage without removing the tank.
07
Direct Bolt-On Installation
Designed to mount to factory locations using original mounting points. No chassis cutting, drilling, or permanent modifications required.
08
Individual Serial Identification
Each tank is marked with a unique serial number for product identification, quality tracking, and authenticity verification.
Weight & Material Engineering
Designed to reduce weight without compromising strength, ideal for long-range and overland use.
