I need to dig out my physics text book - since when the location of an 'air' chamber will affect pressure. I think it is the length/diameter of the fuel line that affects pressure, the longer the lin ...

Yes, length and diameter of the back pressure line affects pressure.
Many people know about the legnth, but overlook the diameter of the pressure line. ; )
Regarding the pressure chamber:
If the car is immobile, having a pressure chamber or not,
or the placement of the air chamber is not crucial.
Yet, if it is placed on, say a GP buggy that is cornering above medium speeds,
then the decrease/increase in fuel tank's air pressure is a known issue. =)
To keep things simple,
you will notice the air/fuel mixture getting much richer when you turn one direction,
and much leaner in the other direction.
Having a pressure chamber in a strategic location helps "buffer" and minimizes this effect. |
