Carrying additional Petrol - where and how to

This is how I carry extra 40L's during the cooler months and never had a problem. I do get rid of it as soon as my fuel tank drops 40L's.

If using Jerry Cans wraps them in carpet using 100 mph tape so they don't rub,it alway amaze me when you see the big time 4wd drivers in magazines with no protection on them.

G'day Wacky,
On the roof is fine from a legality stand point and far safer than on the rear bumper or in the car which has obvious risks.
The thing to consider is to not exceed your vehicle's roof maximum weight carrying abilities by having them on the roof. Other than that, ventilation is fine, don't over fill the jerry's (yes you can fit 24 litres into most 20 litre jerry's but don't) and lash them down tight to prevent rub through or movement.
Be sure to check them every time you stop for a wee break and release the pressure if they start to balloon out.
At the first available time, transfer the fuel into your main tank.
Store the funnel/spout in a dust free environment and if caked in crud, rinse off around the jerry's spout before decanting fuel into your vehicle.
Make sure the jerry's are refuelled on the ground to prevent static arcing and spilling fuel over the roof of your car.
Hope that covers all the do's and don'ts.
I actually made up a jerry holder out of an old bike carrier. Cut the goose neck part off and welded a metal carrier onto the upright part. I leave the jerry empty and vented until the last fuel stop before hitting the remote stuff. Not ideal, but keeps the weight lower and YES, it strictly isn't legal when full of fuel. It does however also fit a 20L water jerry which frees up space in the car or on the roof rack.

Fab.

Just out of interest, what is the current fuel capacity of your vehicle.

I would suggest if it is going to be a regular thing when you do trips that a dual rear jerry can holder something like MCC 4x4 Accessories sell they have a few different versions of jerry can holders. It would be a lot safer keeping weight down low and better all round for stability especially on a 4WD. It's easier than swinging 20 odd kg above your head and risk slipping on your side steps etc. I have never used plastic jerry cans for fuel only steel and they are dearer and can handle the heat.

Fitting a larger auxiliary tank is a much safer and easier way to go. Where do you intend to go that 150 litres will not be adequate?

For remote trips we carry 4 extra steel jerrycans up on the roof. Some carpet underneath to stop rubbing and well strapped down. Emptied into tanks as soon as there is space. Not an ideal arrangement but it works and has done for a number of trips without any problem.

Cheers,

Val.

hi wacky races
I had a petrol patrol for 15yrs , an to go anywhere in the outback
I had to carry fuel , I made up a wooden box that fitted neatly across the roof rack
the jerrys sat on wood ,no rubbing problems , if I stored them on there back with the lid up , I could get 18lts in to them an I could open then on flat ground an syphin
the fuel with out lifting them of the roof .I to was very aware of lifting things on an off the roof , the box fitted 7 jerry cans neatly with carpet between them . didn,t have any problems , have travelled the CSR, Simpson numerous times an lots of other trips .
make syre the seals on the jerries are good ,
cheers mechpete

If you don't do enough remote travelling to justify a long range tank, Wacky, then I'd be looking at a number of 10L jerry's, rather than gut-busting 20L ones. At Supercheap they've got many different shapes and sizes (and colours too!). "Plastic" jerry's are as good as steel ones these days, especially the Rheem brand ones. Rheem ones can swell up in the heat, like the Michelin Man's face, and still not burst, or even leak.

Use some of the storage/carrying methods advised above, and you should have a good trip, with few fuel worries, and your back still intact! :-)

Heres an indication of having too much weight up top https://www.youtube.com/watch?v=Sq5Kc92fFpM
