Tired of that sickening fuel smell in your cabin? Is the constant buzz of big external fuel pumps driving you crazy? Maybe you're looking to switch to E85 and need some extra fuel capacity without sacrificing boot space... One of our High Capacity Fuel Tank Packages is going to solve all those issues for you!
Designed & fabricated in-house as a direct bolt-in replacement for your factory tank setup, our packages are available with your choice of single, double or triple in-tank Walbro pumps in various sizes to suit your application & are E85 safe! Off the shelf, this RX3/808 high-capacity Fuel Tank & Pump Combo is designed to bolt up to the factory mounting points and utilise the original external fill point as per factory & we can also supply you with a custom-fabricated filler neck as well to complete the upgrade - See extras tab

All fuel tanks come assembled and ready to bolt in & plumb up and are now offered with two fuel level sender options - one for use with the standard OEM style analog gauge or a high-range option for use with a digital dash that is able to display a far more accurate and precise fuel level.

*Please note - While a spare wheel cannot be stored with our standard tank installed, we do offer a custom option with a slightly smaller capacity, built to accommodate the spare wheel - See Spec tab

Complete your upgrade with a custom fuel filler neck kit - Available separately

Why put up with a crusty old filler neck and a cap that no doubt leaks fuel over your rear quarter - we can supply you with a brand new, custom fabricated Fuel Filler neck to suit your new fuel tank setup, that bolts straight up as per factory. Each kit includes a billet o-ringed cap, fuel-safe joiner hose, gasket, clamps, hardware and breather hose.
