Auxilary fuel tank Landcruiser

Has anyone got the simplest way of safe use of a auxilary fuel tank
on a landcruiser-Diesel

IE gravity fed or use of 12v pump and senders so each tank can be
isolated just thinking ahead if problems occur.

Has anyone out there got a tank in use and had some time using it
on the road in africa etc.

Just wish to look at the different way's of simplest use on road etc

Do you really need a second fuel tank? Get 10 jerrycans and you solve the problem. But if is a very long trip or a long-term job in Africa or Australia... that´s a solution.

OK, there are two traditional routes for aux tanks for LCs, one is a 50-60l tank up above the spare wheel (assuming you have an 80 or 100) under the boot or a bigger 160-180l tank under the boot requiring the relocation of the spare wheel.

The factory arrangement (available in Aus, etc) is to have a 50l aux tank under the boot and then a solenoid (actually a pair of them) so that you can switch the feed to the engine from one tank to another.

The larger 180l Long Ranger Tanks are designed to operate on a similar basis and you can either go down the Toyota wiring route (expensive) or use a 3rd party solenoids. Either way with these larger tanks you need to relocate the spare wheel which in itself gets very expensive.

FrontRunner do a small aux tank (62l) that sits above the spare wheel and acts as a header tank to the main tank - this is by far the cheapest route.

They also do a larger (180l) tank that operates with a transfer pump.

On top of the tank options is the filler options. The FrontRunner small tank is just a case of hacking the existing filler where as for the others you need to be able to fill one tank or another. Personally I prefer to just go down the route of the factory double filler, but I know some others have gone down the route of hacking the existing filler and welding into a Y shape.

Overall I'm not a great fan of the FrontRunner sub tank because it does sit very tightly between the chassis and body, but does fill a gap at the 'budget' (none of them are cheap) end of the market.

I much prefer the belt and braces approach of using a solenoid for switching between the tanks as well as the nice factory double filler with valve so you can keep the fuel seperate.

Also consider getting a Walbro pusher pump fitted - we find that people often end up running out of fuel more often with two tanks because they tend to be slow at switching over - the pusher pump takes the hassle out of bleeding the system.

I made my own aux tank, 160L, under the car where the spare wheel was (HZJ75). Drawings for the tank are on [www.buschtaxi.de] - The european site for Toyota LandCruiser, HiLux, 4Runner, Megacruiser...: Herzlich willkommen I fitted it like a tripod to prevent torsionstress on the connections, two connections at the back under the chassis cross member on which the bumper is fitted and one U-bolt in the front middle over the cross pipe between the two chassis beams (above the axle) Made an extra filler opening in the side of the car and installed a manual 3 way valve in the fuel supply of which the handle sticks through the floor near the driver seat. I can switch between tanks while driving. An aux tank does not need senders and all that crap, just complicates matters. Always empty the aux tank first and then switch to the original tank, no problem. I did 60K Km in Africa with this tank, no problems at all. It is the same concept as the Frontrunner tank but mine cost Euro 150,- including all and a couple of weekends welding and fitting.

I've got a long ranger on mine and frankly, I'm not impressed. They are supposed to be bespoke to the vehicle, but didn't come with the required fittings to mount it, and it's not properly baffled so the fuel slops about and could lead to fuel starvation problems going up hill as a result. also the shape of it, being square at the front rather than profiled and hanging low meant I had to get a bash plate made up to protect it.

Given the cost if I did it again I would get someone like allytanks to make a proper bespoke design, which would cost about the same and fit better.
It only gives me an extra 65 litres, so about the same as 3 jerrycans which is what I generally carry. It's much better in a tank. cans would usually go on the roof, so a lot of weight up top wheras a tank is low and central to the vehicle. and in a tank there are no problems with duties crossing borders. I wouldn't want to carry more than 3 cans on the roof so now, if I really need it then I could carry a further 60 litres on the roof, giving me 125litres extra, but I've never needed that much.

The tank is a simple gravity feed, but it takes about 30 minutes to flow from the main tank to fill the aux so it makes brimming the tanks on a single fill impossible.

Also, if I hole the tank I lose all my fuel. Personally I would avoid all the fancy electronic tricky of solenoids, more to go wrong, and have a simple manual tap so if you whole your lower tank you can isolate it from the other tank so you don't lose all your fuel before repainting it. Ideally, if I really need more range I'll get a bespoke tank to replace the main tank and spare wheel and mount the spare ona carrier. That would give me about a thousand mile range which is kind of the target I have always had in my head.
