battery next to fuel tank in rear?
Just wondering; would it be a bad idea to place the battery next to the fuel tank in the rear of the car? I can seperate them by a 1 inch
"wall" if needed.
My motivation would be; it's good for weight distribution, and cleans up the area in front of the scuttle. And I do have space next to the tank.
But obviously; what would happen in a rear end crash? Is it extra dangerous to have the two together? Can image it is, but would like confirmation
from someone who knows....

Depends on the tank and the battery case, I had a 8 gallon fuel cell mounted next to a Skidoo battery in a metal case in the trunk of my Datsun 1200
race car, flipped it several times at 120MPH, major impact right rear corner were the battery was. Repaired the car and finished third in Canadian
Road Race of Champions two hours later.

If I'm not mistaken -
Battery Acid + Petrol = Bang 
So make sure you have proper fuel cell.

Only with twin tanks, then there less than a foot apart.
. Just a thought how many modern cars have the battery as close to the tank? BMWs etc tend to have the battery in the inner wing and the tanks are
normally under the car. IMHO the passengers foot well may be better?

My Jags both have them in the boot. I have heard of locosters putting the battery in the rear inside an aluminium box. Thats probably what i will do
to help with weight distribution 
How long can i resist the temptation to drop a V8 in?

MGBs had them mounted close to the petrol tank and I've seen a Mercedes with battery under the rear passenger seat.

This
Would indicate that the presence of acid would not be a factor in causing an explosion or worsening the effects of any petrol spill, other than the
possibility of sparking.

Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!

eh?
my A-level chemistry is way in the distant past but I'd be most surprised if battery acid - mostly water with some sulphuric acid mixed in an
any hydrocarbon would react so violently as to combust. It would be a terrorist's dream come true if it did.
