Hi all,
Going to replace the current midget fuel tank on my fury. I'm looking at getting either a baffled or foam filled as currently it does suffer with
fuel starvation below 1/4 tank on tight corners.
Has anybody done the swap that can either recommend me a tank that fits, or has the measurements to hand?
Thanks
I made my own `big' tank many years ago as the ones available at the time just didnt do it for me - I allso lowered the boot floor for more
camping gear space . Mine is 45 litres , baffled and with an in-tank pump .
Do you have any more pictures of the chassis. I would be interested to see the layout.
Thanks.

I'm making mine. It's going to sit in the transmission tunnel and in the space just before the rear axle. it will be designed to consume as
much of the transmission tunnel volume as possible but with a good inch clearance for the prop. I'm getting back into my cad software which will
take a volume and turn it into the most efficient flat folded shape to then be fabricated into that volume.
The basic plan is a baffled tank, just like the sump i made, with a small (5cm dia) sump at the front, fuel take-off at the top and attached to a pipe
going down into the sump. Then I should always be guaranteed some fuel no matter what angle the car is at when starting if on a fairly empty tank.
I'm not going to put the swirl pot in there (I want the volume for fuel).
I like what you did lowering the floor, but I don't want the tank there anymore - too much polar moment of intertia for me; 20kg of fuel slung
right out at the back.
I had a midget tank, but after a while it started to rot, and never was a brilliant fit.

Some nice looking tanks! It would seem custom may be the way to go.
If any of you fancy making another could you PM me, as would definately be interested.
FuryRebuild,
Have to say this but I'd be extremely worried having a fuel tank alongside me inside a tunnel with a spinning propshaft.
All might seem well, but I once hit a severe undulation in road at speed and the shock broke a gearbox rubber mount causing the prop to hit all sides.
Luckily no other damage done. Even if it didn't break I suspect the prop would have moved quite a bit.
The undulation wasn't visible at the low level of seating in the car. 
Plus I think if you intend 'eventing' then a canny scrutineer wouldn't allow you to compete.
tasmod - call me Mark 
I'll get the bluebook out before I design anything.
There's a lot of space in the tunnel and especially up into the void behind the seats and above the rear diff- I think I'll use quite a bit,
but maybe not wrap the prop in a saddle of fuel. I also have the option to put protection in over the prop. My fury is IRS, so the engine, box and
diff are rigidly mounted, apart from the couple of mm give in the mounting bushes. As such, the prop has nowhere to go really. If the prop did let
loose at the centre UJ, I'd have a lot more to worry about than the tank.
As far as I can remember, the book states that the tank must be able to vent dripping fuel out of the car (as in, it can't be a tank in a sealed
enclosure). What I sincerely want to do is move the mass from where it currently is (beyond the rear wheels) because high polar moment of intertia is
one of the worst mass-effects on handling.
I've yet to have a scrutineer check things like that - in hill-climbing they are restricted to what they can see. However, putting one over the
scrutineer and against the blue-book is stupid. The book's advice is there to protect people.
So, thanks for the advice - I think it is sound and at the moment I'm mulling my options. One of the advantage of doing it in cad is that I can
change my mind any time up the moment I email the drawing off. Another advantage is that I have the time to create a complex shape to use the volume I
have spare rather than have to deal with the financial necessity that is often the case when an off-the-shelf unit is a compromise.
Hi Mark,
I didn't realise your car was IRS I had seen Claire's car which looks like a live axle. Without seeing it I leave it to your choice.
Are there any bare chassis pics anywhere ? The Fury is a car I would consider next.
I hillclimbed about 10 years ago and still hanker to try again. I guessed the avatar was at Harewood, looks like the corner I spun off onto grass in
icy conditions. Just as you climb up from the lower part of track at the bottom of the hill.
The scrut's have power to stop you competing in an event on safety grounds, then you have to appeal to MSA which costs !! They know 99.9%
won't anyway.
I had one who did it to me until I could bodge another bracket for the silencer, even though there was nothing wrong with the original single rubber
mount on the silencer. Fortunately other competitors helped out.
