Bladdered Fuel Tank
Discussion
try fuel safe ,they come from the states and i got mine for the sag in about 3 weeks all made to my measurements and the price was very good as well (mike luck 01527521050)atl wanted 2x there price and premier just are a waste of time i was waiting for about 15 weeks they dont ring you back so told them to f off
The 60l cell that ginetta use might be a standard size atl saver cell..
If i get chance to crawl in the back of the truck I'll measure up the one in my car.
The costs do mount up quickly though..
the basic 60 atl is about 480 but you need to add an alloy box to put it in, the ideally an internal collector, and submerged fuel pumps, as I said mine even has the pressure relief valve in the tank, so there is no return from my fuel rail now, just the feed from the tank.
you could use a pipe from the standard filler into an atl cell below it but this was always a week point on the stock setup, take a sideways hit and the filler can break away from the tank, when the passenger bay cover moves.
I just had an extra metal box made to cover the fillers and use the filler direct in the top of the tank, and dont use the passenger bay cover.. It did mean I had to firewall the oil tank under the dash though.
Im much happier that the car is safer now though. the oil tank and battery are separate from the fuel tank by a bulkhead, and i've got rid of all the external pumps, filters, and collectors with their associated pipes and pipe joints to leak !! The tank its self is also much safer than the old alloy one, with a bit more space between the side of the car and the tank.
IIRC Richard Right and possibly Tim's cars both have atl cells mounted over the diff in the rear of the car. That might be a better solution if you want to fit a dry break refuel.

mine was over the diff carrier and inside the cage legs.
don't need the box then...
yep as long as there is a bulk head between the driver and the tank you dont need the box for the regulations, although it is recommended for ultimate safety as it stops the cell bulging on rapid deceleration.don't need the box then...

as seen on tv when Kev G hit the bariers coming out of knickerbrook at OP.
Tanks flew off and out!
No it didn't Andy .. The tank is mounted on its own frame to the rear chassis Tanks flew off and out!
and stayed put !! we have never had to repair or touch the tank after any of
Kev,s misdemeanor ...
A point to note - the flexible bladder style safety cells have a 5 year life and can be extended by a further 2 if re-certified. After that its a new cell. Depends what sort of racing you do whether the scrutineers will ask to see your certificate and won't let you race if your cell is out of date, but can happen. The cells will no doubt deteriorate with age, but I suspect the manufacturers are conservative with the life they put on them.
Have just sent my ATL cell back to be re-certified - I may race at Spa this year and they are very keen on certificates over there!
Hard to believe it's 5 years since I embarked on the LS route and put the larger cell in the car. Where did the time go?!!

Alloy tank (no cell) over the diff and within the cage for me - both in the current car (courtesy of the Hockins) and on my previous car too (now Tims). The latter I had modified as it was originally in the boot with no protection at all around it 
I've got the same dilemma with Martin Crass' old car. In the boot with pumps and lines all exposed with absolutely no protection. I know the car was originally built for hillclimb, but even so, what a scary set up. Looking at best solutions now including relocating back under the tonneau, or leaving it in the boot and adding to the cage to give it some protection. I welcome best suggestions.
