DESCRIPTION

Overview

Long-range outback exploration requires matching your vehicle's endurance to the terrain. When fuel stops are separated by massive stretches of up to 400 km of corrugated tracks, the standard 90L tank simply isn't enough to get you through safely. This under-chassis 35L auxiliary fuel tank is engineered specifically to fix that deficit for petrol-powered builds. Nestled cleanly within the midsection undercarriage, this premium stainless steel system adds critical range while preserving your departure angles and interior cargo capacity. Guarded by heavy-duty armor, it is built to shrug off hard impacts, ruts, and track debris on remote expeditions.

Features

Impact-resistant stainless steel construction ensures elite fuel containment
Supplements your system with an extra 35L of petrol capacity for long-distance remote touring
Smart mid-vehicle undercarriage integration minimizes body roll
Robust integrated fuel tank skid plate handles brutal belly-scraping obstacles
Paired with dual side outrigger skid plates for maximum underbody impact deflection
Specifically calibrated for gasoline fuel vapour and standard line pressure requirements
Clean mechanical layout optimizes ground clearance while protecting critical fuel components

what people are saying...

James T.

I’ve bought cheaper accessories before and regretted it, so I was a little hesitant ordering again. The Epic Off Road product felt solid, fitted properly and looked like it actually belonged on the vehicle. Definitely worth paying for something that feels made to last.

Ben H.

My biggest concern was ordering something online and finding out the fitment was slightly off. Everything lined up exactly as it should and the finished result looks factory. Really impressed with the quality and attention to detail.

Matthew D.

I wasn’t 100% sure which option I needed, so I contacted Epic before ordering. They made the process simple, answered my questions and helped me feel confident I was buying the right product for my Defender.

Ryan C.

I wanted something that made the Defender feel a little more individual without making it look overdone. The upgrade gave it exactly the tougher, cleaner look I was after. I smile every time I walk up to the car now.

Luke W.

Buying accessories for a vehicle like this can be stressful because you’re always wondering whether you’ve chosen the right model or fitment. The information was clear, ordering was straightforward and everything arrived exactly as expected.

Tom B.

I didn’t want an accessory that was purely cosmetic. This has genuinely made the vehicle more practical while still improving the overall look. It’s one of those upgrades you notice every time you use the car.

Sarah J.

I kept putting it off because I wasn’t sure whether the difference would justify the cost. Once it was fitted, the improvement was immediately obvious. Better functionality, better appearance and the vehicle just feels more complete.

Emma R.

From the product information through to delivery, everything felt professional. There was none of that uncertainty you sometimes get buying aftermarket accessories online. The product arrived well packed, fitted properly and matched what was advertised.

Rebecca T.

I love the vehicle and didn’t want to put anything on it that would cheapen the overall look. The Epic Off Road accessory feels considered, well made and suits the Defender perfectly. It gives me much more confidence buying the next upgrade from them.
