BIC performance

Been doing some searching and havent found too much out there.....I am tired of the short range that I get between fills, in the city I get 300-325 kms (187-200 miles) per tank.

I have two ideas, one is to make an small auxilary tank that is linked to the main tank through the tank drain, so it will fill when you fill the main tank. This would be located near the transmission ares inboard of the frame, maybe 10-20 liters. This would extend the range slightly.

The second option (and probably the best) is to remove the spare tire and install a second tank, this would double the range depending on what tank is used. I would use a factory type switch that would run off either tank, similar to what Ford trucks use. Or I could have the secondary tank pump into the main tank for a simpler install.

I want to see what you guys have done, post pics, links, info r what ever. I have seen a 95 F150 tank used, and think that a Jeep Cherokee XJ or a Samurai tank would fit nicley in the tire location and carry 50+ liters of fuel.

Depending on the size of the tank your going to need to put heavier springs on the rear axle. But then when the tank is empty its going to ride like a log wagon. Just remember for every 10 gallons it's roughly 100 Lbs.

If no one has any info here I'd recommend trying expeditionportal.com. A lot of those guys go for 2 or 3 months adventures so someone over there must have some sort of auxiliary tank setup.

Why would you need to do that for 100 lbs? I throw more crap than that in the back on just about a daily basis, and my shocks are as crappy as ever (but not much crappier) - lol.

A gallon of gasoline weighs anywhere from 2.6 to 2.9 kg (5.9 to 6.4 lbs). Its depends on temperate, and the mix of gas, ethanol, and other trace chemicals. You should be fine with the stock suspension setup, and if its not to your liking, then try some larger coils. i see guys using land cruiser coils on their 4runners, that would be a good place to start.
Good Luck

I've started looking around for options at adding another tank. I think I will go with a 6-10 gallon fuel cell mounted in a toolbox in the bed. I'm still thinking about how to "T" into the factory fuel system. Chances are it will tap into the filler and I'd have an external pump to pump over into the main tank. This way should I need to move I can easily pull the whole tool box and put it back when i'm done. Still planning it.

Something to think about.

Also, with your mileage, consider swapping out your mechanical fan for an electric. I have a '91 4Runner that I've swapped a 3.4 into. My mileage on non-winter gas is 425-475 kms per tank. It went up about 5% after pulling the mechanical fan.

The simple and effective way to do this would be to install a ~20 gallon fuel cell where the spare tire is IF you can go without a spare, i personally don't.

These fuel cells can be found on craigslist for quite cheap, I got a smaller one for my MR2 for $40.

Install that in the rear with any cheap used fuel pump you want and then run the lines to the stock fuel pump, most likely T into the stock return line.

Then when you get low in the stock tank, flip the switch for the second tank and it will fill the stock tank back up as you drive.

The above link is basically what i am suggesting

the f-150 tank is probably the best option if going with another tank .. can be used as the main tank or an aux tank .

Ive already got mine ,$40 on craigslist complete .. just need some time to do the install.

Search bruceTS's post where he put a fuel tank out of an isuzu i think in the spot of the spare tire. You could do that then just keep the stock tank too.
