Hi there, I am looking to increase the range of my mini/allow it to have more fuel capacity for the 1275 with the webers when it goes in. I know that the coopers had the double tank, but those are crazy money and has been done quite a bit.
I was just wondering what larger fuel tanks people would recomend to put in, I guess I could go with 2 tanks connected together, or perhaps just replace the OEM tank and put a larger one in its place. I don’t want to cover over the battery (for obvious reasons lol) and I don’t really use the boot, I just would like a larger tank for longer distance stuff, the current tank can do over 300 miles, but it would be nice to not have to worry about filling up quite so much if I were going 200 miles and then back again, the fuel gauge isn’t a very good representation lol
What has everyone else fitted or have ideas about? What about race tanks? how much are they and where from?
The RH tank as originally offered as an option on the Cooper ‘S’ and, from 1966, as a standard fitting, holds 5.5 gallons. It is not cheap, but comes as a complete kit fro Mini Spares and other suppliers. If added to the 7.5 gallon LH tank (early Minis were 5.5 gallons in the LH tank, but I assume yours is 7.5 gall) you will have a very professional looking installation holding 13 gallons. Expect the handling to be a bit ‘odd’ when both tanks are filled. You will still be able to get at the spare wheel and the battery.
There is a self-levelling pipe which interconnects both tanks, so you don’t need to do anything with the fuel gauge, unless, of course, it’s not working properly (do they ever?).

Hmm I will have a look, im going for a sleeper kind of car, the car will be running about 400% more power than stock and I don’t want anyone to know it lol im guessing 2 tanks might be a give away im not running stock.
Also with that cooper conversion, it tucks in the side like the other tank, but wouldn’t that cover the battery?
If you dont want to do the two tanks and you are sure you are not gonna use the boot then just remove the current one. Then fit a much larger alloy tank in the boot!!! However once you have bought it you will probably have spent the same money as on the dual cooper ‘s’ tank lol!
I need both my tanks as my 1964 Cooper ‘S’ 1310 cc historic rally car holds 11 gallons and does about 10 to 12 mpg on stages, 14 mpg on Welsh road rallies and 22 mpg on normal road driving.

Mine has done 48mpg from a 998 on the motorway over the last few days (before it overheated lol) but I can see that with a 1275 running twin webers and a hot cam, its going to do much less lol so I will need something extra, else I will just be dashing from service station to service station
It should still give a decent figure unless you are dropping the gearing down for pure acceleration. Fot a road Mini with a weber and a decent cam, you should still get in the low 30’s per gallon.

It will be running an 1100 sprint box lol so I will so only get 10mpg lol
