Driving across some parts of Australia can mean driving for hundreds of kilometres in complete isolation. And the idea of running out of fuel in the middle of nowhere can be quite stressful. With it’s original fuel tank Vanda could drive around 400 km before starting to look for a gas station. For driving around the city this is great, but for our ambitious plans unfortunately it’s rather measly.
When we upgraded the tyres the spare wheel wouldn’t fit under the car anymore. So we had to have it attached to the back door instead. This left a generous amount of space below the car that would be perfect for a second fuel tank.
So when I found a second hand Pajero fuel tank on Gumtree for 50 bucks it was a no brainer. I chucked it in the car and took it back home.
Unfortunately it was slightly too long to fit straight in. But at 92 litres we could afford having it cut for the expense of loosing a few litres. So we took it to a boilermaker and had 1/3 chopped off. Making it 60 litres in total but now a perfect fit under the van.
Building brackets and plumbing it up
All that was left for me to do was to build the brackets to hold it in place and then plumb it all up.
I used one of those 6-port fuel valves you can find on eBay. It allows us to select between main and auxiliary fuel tank from inside the cabin and even shows the correct fuel level on the dashboard.
All in all it was a very time consuming exercise, but definitely worth it. Our total fuel capacity has increased from 75 to 155 litres – including 20-litre jerry can we carry behind the car -, which means we’ve more then doubled our range and can now drive in excess of 1,000 km.
