Before the light got too bad, we decided to do some car to car photography. I briefly swapped back into the GTA and after a few runs noticed a distinct smell of petrol. We had noticed this before, after fill ups, when it appears to be caused by the heavy petrol vapour settling in the luggage well alongside the large, under 'bonnet' filler and then finding its way into the vents as you drive off. But this was more worrying. When we removed the filler cap there was a strong blast of warm petrol vapour from the tank! A later check revealed nothing, and it never happened again. We can only assume that the constant low speed work involved in car-to-car pictures meant that heat was not being dissipated fast enough from behind the front mounted radiator and was warming the petrol. Enclosed, it is probably not dangerous, but there was a hell of a lot of vapour coming out of that warm tank when we took the filler off, and it only takes a spark!

Once the bottom of the U bend is primed, water does not sound ideal, but petrol may evaporate away, the vapours will be trapped in the tank. As the tank level lowers under normal driving conditions, a small vacuum will be formed air air bubbles should slowly creep in. On a hot day when the fuel and vapours expand, the small pressure should be enough to bubble out through the U bend. So long as the height difference between the 2 Us is small, the pressure required to vent will also be small.
HOWEVER, I have no idea if this idea contravenes any manditory venting requirements and I accept no liability whatso ever if you were to try this "idea".
sorry about the crudeness of this diagram.

I thought it was a pretty reasonable idea/improvement.
Any way....I'm snowed in today. We had about an inch yesterday evening and it is icy today and I live on a hill.
