You know those expensive controllers that we can buy to vary the voltage load to our fuel pumps?

aeromotive makes one, weldon makes one (theirs is specific to their pump however and function different), and barry grant makes one

here is one YOU can make

i found it searching around for air/water stuff......i plan to buy one and use it to control my pump for my air/water setup

just figured i'd pass it along

 

I would think on start up a big pump uses more than 20amps, maybe not

 

could be, i dont know. i plan to use it to vary the speed of my intercooler pump

im no electrical engineer but i figured i could post it here for people to see and maybe even modify to work with fuel pumps
