Car Forum / Australian Car Forums / 4x4 Cars (Australian group) / March 2005Long Range Tanks and Lokkas
I've been told that long range fuel tanks that sit under the fully laden vehicles rear may impede traction on sand dunes. The reasoning is that with the extra weight on the back, the front wheels may not get optimal traction. Sounds logical but I'm not convinced. Does anyone have experience with the Lokkas that are sold by 4wd systems. I can't afford air lockers and was wondering if Lokkas are worthwhile? Do they impede steering or make noises as you corner? And to invite a flood of responses, install in front or back ? Cheers Jim >Sounds logical but I'm not convinced. No it doesnt. > >Sounds logical but I'm not convinced. > No it doesnt. Whats illogical? Laden truck bouncing up a sand dune .... Take a look at the 100's of thousands of 4b's out there over the years with LRTanks that do the Simpson, Robe, Stockton, etc etc, and have no issues. If the tank was 4 ft behind the axles yes then I may agree. >Whats illogical? Laden truck bouncing up a sand dune .... Thats what I thought, however ; "This is not the type of tank you need for a stock route trip. The extra weight of fuel behind the rear wheels , multiplied by the distance of the centre of gravity of the full tank will give you an enormous moment arm. Every time you move up a sand dune the C of G will move so far back your front wheels will tend to move off the ground. Stay with a centre mounted tank if possible" Ron Guard, "The CSR, A travellers guide."

Laden truck bouncing up a sand dune .... how big is the long range tank and what vehicle is it fitted too? the weight of the vehicle will have to be included in this as a light weight vehicle will be affected a lot more than a heavy one also the wheelbase affects it too my cruiser has a 50L sub tank right above the spare wheel(as far back as it can get) on a trip to Double Island Point two weekends ago I only had fuel in the rear tank, and the 12V cooler and a few other things for a day trip with kids, had no trouble getting along the beach at high tide(1 hour in second at 30kph) I doubt a second tank will really affect even a Hilux that much 50L is only around 40kg, bugger all in fact the average bullbar would counter balance it Kev > Thats what I thought, however ; > "This is not the type of tank you need for a stock route trip.

Since the main is only 90l, thats 180kg sitting rear of the axle. Add to that a loaded cargo area and there's some serious weight .

Ummm, The long range tank in a Landcruiser is an additional tank that is situated approx over the centre of the rear axle in the 75 series cruiser. I dont know of any factory long-range tank setup that actually removes the factory 90L main tank and adds a larger one. They simply add a larger second tank. Given most of the Landcruisers (both wagon & trayback) for the past 10 years have had the capacity for an additional tank, I doubt many manufacturers bother with trying to replace the factory original main tank. No doubt I could be wrong, but I havent seen very many with a larger main tank. Having an interesting time getting prices on a Landcruiser trayback from Toyota dealers at present. We are replacing the POX-BOX NAVARA in the next few weeks, and it will be gone for good...Not that I'm dwelling on it or anything...I have been advised by one dealer that the standard fitment for the 79 series cruiser trayback is a 90 + 45L tank arrangement, and did I want longer range than this? I requested 90+90L, as we have in our 75 series Landcruiser trayback, and he tells me the largest rear tank available is a 65L one! Pigs arse it is! Our roo shooter has an 11-month old trayback from the same dealer fitted with 2 90L tanks! Once I get all the quote details, we will be following this little tidbit up with all of the dealers quoting. I am adding it to my list of followup questions... And on the subject of fuel tanks.....Talking to a truckie based in the town just north of us (Aramac), I note his Western Star has 3 300+ L fuel tanks down the drivers side. I ask Charlie how much fuel does the rig carry? 2000L on the prime mover, and a 'spare' 900L under the second trailer! Now thats fuel capacity! He tells me the truck (now 5 years old) has just clocked over 1,000,000 kms, and he is thinking about trading it in for a new one...

Yep; went and had a look at the 75 trayback here(1995 Model), and the tank indeed sits over the rear axle at the front, but hangs down just behind it. I'd put most of the weight as directly behind the rear axle. > > know of any factory long-range tank setup that actually removes the > factory [quoted text clipped - 4 lines] > > They have included an additional tank for at least the past 10 years Maybe in the wagon, but in the 75 series trayback, the long-range tank, snorkel and instrument pod that went on the dash was an additional extra bundle, but often supplied to sweeten the deal. I went looking for another instrument pod last year, and the reply from 4 parts dealers\wreckers was they would only sell the whole kit, as they were a popular kit, and getting hard to find. Additional tank on the 75 trayback wasnt a standard fit; it was an option. > > have had the capacity for an additional tank, I doubt many manufacturers > > bother with trying to replace the factory original main tank.

I didnt have any reason to doubt his word as far as his fuel capacity(not really something I'd challenge a truckkie on anyway!). Given six of them at around 330L comes out around 2000L, I cant see them being 500L tanks. However, I have been known to be wrong (many times). I will take more than a passing glance next time. Maybe I should nick a tank-full, and measure it! And then run like hell! Cheers, Rod.......Out Back If you CAN run carrying a 330l drum/tank of fuel then you bloody well deserve to have it David > Maybe I should nick a tank-full, and measure it! > [quoted text clipped - 3 lines] > > Rod.......Out Back Well Rod most trukies tanks are approx 500lts mate. > Fig, > [quoted text clipped - 15 lines] > > Rod.......Out Back what would you know ya wally our trucks have 330 litre tanks mostly although mine has 2 600L tanks, big rectangular ones, only have about 5 inches ground clearence and seeing as we only do a max of about 500klms a shift I think they are a bit of overkill Kev "Figjam(cable)" wrote: > Well Rod most trukies tanks are approx 500lts mate. > > > Fig, Yeah comin from someone who cant even get up a small mound that a bazookie can do without loosin a muffler. :P > what would you know ya wally > [quoted text clipped - 11 lines] >> >> > Fig, "Figjam(cable)" wrote: > Yeah comin from someone who cant even get up a small mound that a bazookie > can do without loosin a muffler. > :P got further than you did ya peanut at least my wheels where still on the ground :) Kev Bwahahaha keep laughin > "Figjam(cable)" wrote: >> [quoted text clipped - 10 lines] > > Kev Yeah but tanker drivers arent real truk drivers.

The DAF I drive has 2 350lt tanks. Daryl What is the deal with the pumps. I had one stop at 1000 once, had to walk in and get it reset. Then there are the attendants that go off at you if you use 2 pumps on the same side... It's so hard sometimes.. >"Figjam(cable)" wrote: >> [quoted text clipped - 3 lines] > >Daryl > What is the deal with the pumps.

I've never had that problem if they make you walk in to have them reset, or complain about you using two pumps just don't go back there, if they are that ignorant of the needs of their customers, they don't deserve customers Kev Jim schrieb: > Does anyone have experience with the Lokkas that are sold by 4wd systems. Which brand, which vehicle? I drive LockRight in a BJ42 front and rear which makes this workhorse unstoppable. Locking hubs front required, and a '2L' modification makes very much sense - power steering also. They do a ratcheting sound, but compared to ARBs I don't give a damn. Nothing manually operated comes even close to this ease-of-use and bang-per-buck. No thinking on activating the lockers, just head for the dirt... > I > can't afford air lockers and was wondering if Lokkas are worthwhile? Do they > impede steering or make noises as you corner?
