actually, i think the large volume of fuel filter lowers the pressure coming from the exhaust pipe to the fuel tank. Just imagine how much pressure the exhaust pipe is producing while reving ( you can test it by getting your hands in front of the nipple of your pipe). lets say 10% of that pressure goes to your fuel tank. ( i think youre correct) it only applies during full tank wherein the volume of air in the fuel tank is low and the pressure woulds be high.

The purpose of the volume canister in the pressure line is the smooth out any pulsing you might get. Since air compresses, a large volume of air won't pulsate as much.

As for the fuel getting forced into the pressure line during off throttle right hand turns, it shouldn't happen. Most fuel tanks have the pressure fitting in the cap so that doesn't happen

On my V-One S, the pressure line connector points the the LHS of the car, so going hard around a RH corner, with a full tank (And that what were discussing now), with the forces on the car, I think it is likely fuel would travel down the pressure line. So by adding the large fuel filter, or a loop of tubing, that increases the volume of presurised air, so when you back off the throtle, while there is some pressure drop, it not enough to interrupt the supply to the carbi, thus inducing a leaning of the mixture greatly, allowing one to power out of the corner.

Coments ?

to summarize,
a loop or large fuel filter in pressure side will reduce foaming on fuel produce by eratic revving.
