Yeah, that's what I was saying. Even if this excess gaseous gasoline pressure was causing too much line pressure there is always the fuel pressure regulator to control it.Originally Posted by jtwmechanic
I agree. This is usually the case.Originally Posted by jtwmechanic
There is a charcoal canister. The fuel rails do have a return line.Originally Posted by robertisaar
The gas tank is two pieces of stamped sheet metal welded together around the edges. Technically if the seams were in the right place the added weight of gasoline ontop of them would cause a slight increase in stress at the seam. However, because of where the seam is (basically parallel to the plane that represents the top of the fuel level) this doesn't happen. This is why on giant water tanks you can see the seam in the same place (around the tank, horizontally) and not vertically around the tank.
I haven't heard of automobile gas tanks bursting on their own. It just doesn't happen.
