Default How to proper wire external pumps

Hi friends!!!!, just a short note to let all your suggestions on how to properly wire my two externals pumps

Car is a Gc8 with N/A ECU, so no controller at all, right?

I want them to prime the fuel system when swicthed on as the intank one does without screwing the stock electrical fuel related components...

Thanks for all possible diagrams, links etc

DJ

Easiest way would be to run fused (~30A) (how big are your external pumps?) 10awg wire back to the pumps, through a relay mounted in the trunk.

Switch the new relay off the output of the fuel pump controller. You can wire the relay switch in parallel across the controller output.
