Gentlemen, there is nothing inside the pumpt that controls the output power of it ! This is a stupid brushed motor that spins depending of the counterpressur that it sees. The unused pressure is transformed into fluid flow by the pressure regulator. And - a higher resistance (bad connector, thin wire, oxydized fuse, melted fuse holder) reduces the current. NO need to believe me, I just make my money with fans - which is nothing else but an air-pump. BTW - powerfull fans do have electronics inside to limit the max speed by PWM - therefore they can keep the power constant. When the voltage goes down - in certain limits - it draws more current. Again - nothing like this in a fuel pump. Yes, I even cut an old pump open to see how it works. Oh another example - the interior fan - it uses resistors to reduce the power, position 1 and 2 don't even require an extra relay...strang if - according to you - the current goes up ?!?!?!? :-P Have fun ;-) Elvis & 6548 --- In dmcnews@xxxxxxxxxxxxxxx, Ian <texas.twister@...> wrote: > > Ditto! > > Ian Yanagisawa > > On Jun 18, 2013, at 12:53 PM, JP Hindin <jplist2008@...> wrote: > > > > > > > On Tue, 18 Jun 2013, Elvis wrote: > > > This is a very strange theory, that a lower voltages kill something and draws more current. > > > > This one I /can/ answer - the work of the pump doesn't change, so it's > > fixed - the laws of physics state that by lowering the voltage, the > > amperage must go up (Volts x Amps = Watts).

This will eventually burn out the pump.
