Crap... The fuel pump wiring on most vw is pretty direct and runs through a relay anyway. And they normally tend to have a healthy voltage. Won't give any gain what so ever imo. Neil.
You have more pressure at the reg than you will ever need, that's why there is a regulator, to drop it down....
pressure and flow rate are two different things though. flow rate is what will suffer with lack of voltage. the voltmeter test things on that ad looks bollox. it would have to running through tooth picks to knock 3 volts off. looks more like a with engine running, without engine running type scenario.
