Hi There,
i was thinking about putting my fuel tank right at the front between the wishbones, does anyone know if the IVA man will be happy with that or has
anyone done this and it worked out ok???
What do you think?
I realy don't like the sound of that at all. Most crashes seem to happen front end first, as the tank empties the weight on the front wheels will change and loss grip although progressively. As for IVA I think that will depend on the views of the tester but I think it might raise a few eye brows. Is there any reason why the tank can't go some where else?

A very dangerous place, but you have to tell us what you are building!
Its here on a J15 / Riot.
Behind the line of the wishbones.
It's not that dramatically dangerous!
Rear-end shunts are ten-a-penny and no-one seems to be all that concerned about there only being 1.2mm of ally sheet between the car behind you and
your fuel tank!
Naively I assumed many mid rear engined kits had tanks in the front. My old 911 did and it fair to say he handling was much improved with a tank full
of fuel. Certainly noticed the under steer when empty.
If the chassis at the front is designed well why s it so much more dangerous than where it is my Indy where essentially it is unprotected other than
by the fibreglass rear panel?

In an ideal world, it would be as close to the centre of the car as possible, so my vote goes for the passenger footwell. However, when i next build a car the engine will be in the footwell, so the tank might go under my left elbow, over the prop.

11. A Fuel Tank must not be located in, or form part of the passenger
compartment, or other compartment integral with it and the bulkhead that
separate the passengers from the fuel tank must be free from holes through
which any escaped fuel could travel.
and
14. Fuel tank filling points must not be located in the passenger compartment,
luggage compartment or within an engine compartment.
If it's a 7 then you'll need to be careful of the rules around heat sources. Sticking even more weight up at the front won't do you
any favours either.
If it's mid engined then all will be fine so long as it meets rule 8 all will be fine.
Section 3A of the IVA manual has all the rules.
Can't see why it's any worse at the front to the back from a safety point of view - at least it's your fault if it all goes pear
shaped.
