Aux fuel tank

[MontrealRR90]

has anybody rig up an aux fuel tank on a rangie 88 to 94.I only get 215 miles a tank a 55 mph on an expedition which limits. I have four gerry cans with an expedition exchange holder but would there be a benefit in rigging up an aux fuel tank and what would the negatives be regarding offroading?

The negatives I would envision are extra weight, which doing expeditions as you stated is highly coveted. You would have decreased ground clearance as an extra tank would be under the vehicle unless you did an interior tank but that creates its own problems (leaks, harmful vapors, filling would be troublesome etc). The extra weight needs extra power to move it around and that takes extra gas. You should maybe look at doing an LPG conversion like they do in the U.K. I hear they are very nice and they have interior mounted tanks, and smaller tanks to locate under the sills. Either way you are looking at less room for gear or decreased abilities off road.

were would i find these guys LPG ?

I wonder how costly it'd be to have a fab shop build up a second gas tank to fit in the available space underneath! 215 mile range is no good on expedition trips! The sill mounted gas tanks should work well and since you're into expedition and not rock stomping, I'd suspect that should work out fine. As far as extra weight being carried, either carrying it in gas cans or having an aux tank sorta cancels out this issue, IMO.

well actually i do both exp and offr. The extra gas on top does not bother me on the roads but on an incline offroading its easier to tip over.Even if i have a good size rack i still have two spares 245-75-16 and tons of camping gear because my wife comes along ! two dogs
so if i could manage less space on top it would give me some other alternatives.I also carry tools ans spare sparts.Nerver have enough room

pics of the rack

heres a few pics to give you an idea!

Can I get more pics of the front winch mount? I have one off a disco I am picking up in a couple weeks and I need to know what is required to mount to a RRC in the best way possible.

Thanks
Ron

Any boatbuilders near you? I had a boat builder who specializes to Aluminum tanks, build me a custom tank for my D-90.

Aux Fuel Tank for 4.6 shown

I asked a similar question for my LWB a few months ago, and did not get too good an answer. Here is a link from rangerovers.net noting a tank for a 4.6.

The problem appears to be that nobody wants to be responsible for such a tank, and therefore there are none. I looked on the web a bit, but found nothing other than a few D90 tanks under the passenger seat.

Let us know of you come up with anything.

LPG would be interesting. If your motor blows, you could convert to Diesel?

tks guys i will look into maybe a boat builder like dmarchand said.rr.net has an option but it's from australia a bit far for me if theres something wrong with the tank eventually. Can't be that hard to fabricate but with RR you never know tks again

hey Ron i have not had the time to take the pictures i promise that wenesday night i'll post them.

Nicholas,

The extra weight needs extra power to move it around and that takes extra gas.

yeah, extra 20 gallons of gas will mean extra 20*6/4500 = 2.67% of weight, which in its turn will require extra ~2% of power (I may be overestimating it), and doubles the usable range.

You should maybe look at doing an LPG conversion like they do in the U.K. I hear they are very nice and they have interior mounted tanks, and smaller tanks to locate under the sills. Either way you are looking at less room for gear or decreased abilities off road.

you're envision extra weight as negative, you are concerned about harmful vapors and fumes, and suggest doing an LPG conversion, for a vehicle that's going to be used in an "expedition?"
That's a good one.
Sorry man, that's a post for a post's sake.

I'm only trying to help.

Hey Peter, If you come up with anything, see if they can make a few

unfortunately, there's no room on the Rangie to put another fuel tank safely. One step forward is to use later-year RRC or D1 tank, which is 23.5 or 24 gallons. Another is to fabricate a tank to fill the right-side rear quarter panel - that may be good for 8-9 gallons, and the filler could be placed on the same side as factory. The weight of the fuel tank in this location will somewhat balance out the stock spare tire. If the spare tire has already been relocated to the roof rack or tailgate, left-side rear quarter has more room for an aux fuel tank.
The next issue would be how do you deal with the fuel pump and plumbing; if the aux. tank is placed above the filler neck of the main one, you can't just run the line from one to another. I would use a little low-pressure electric pump to pump gas from the aux tank to the main - it can be turned on once you see that the fuel level in the main tank is low.

Needless to say, all and every fuel connection need to be done very carefully. Fire danger aside, breathing gasoline fumes all day long is not a life-enhancing experience (to the most of people, that is).

SC made me think - with the fuel tank recall work currently going on, you may be able to get your hands on D1 or 94-95 RRC tank for next to nothing.
