i want to put dual bosch and i will like advice in how to wire them up. I have a microtech lt10c and I can wire one pump to start with the ecu and another to start at a set rpm by the ecu, or I should connect them to be always on ?

 

thats a cool idea!

 

Anyone can tell me if its better to have both pumps running all the time or if it will be better to start the second at high RPM when i need more fuel?
