Hi guys just wondering if anyone has fitted a bigger fuel tank in their hatch,
I want to do this but not sure where to start,
I would love to double the size but not sure if a 50 ltr tank can fit.
Fuel tank
Easiest way to double the tank size would be to remove the spare wheel and replace it with a second (auxiliary) tank or fuel cell.
I don't think there's any other option that would be cost effective, besides carrying a 20L jerry can in the back.

The factory tank is shaped to take up all of the available space between the rear axle and cabin floorpan. The only way to go bigger in the same space is to have a deeper (taller) tank, and that would impede ground clearance. To double the size that way the tank would basically be dragging on the ground.

You should get around 400kms to a standard tank. Surely that's enough range to get you to the next petrol station.

To replace the factory tank, or to install in addition?

Your only two options for a new tank are to source one through Suzuki, or have one fabricated.

You'd be surprised at what parts Suzuki can still source from Japan, and probably equally surprised at how expensive those parts are.
But yes, either genuine Suzuki or a custom fabricated tank is going to cost you a bomb - problem is that there is no alternative if you want a brand new tank.

The tank is held in by three bolts, it is a very quick job to remove it.
