Wiring for primary in-tank and surge tank pumps

Recommended Posts

Trying to decide on the best way to wire up the primary in-tank AEM 340lph pump and the surge tank Bosch 044 pump. 

 

I currently have full aftermarket power supply setup with circuit breaker, relay feeding into a fuelpro pump speed controller that I'm not sure what to use on. 

 

Options would be

 

A) Leave the current factory speed controlled supply setup going to the in-tank pump which should be ok with the lower amp draw once it is running as a low-pressure circulation pump and hardwire the 044.

 

B) Hardwire the in-tank pump and use the aftermarket speed control setup on the surge tank pump assuming they are happy with lower voltages.

 

C)Hardwire both

 

D) Factory speed control the in-tank pump with the factory setup and speed control the surge tank pump using the aftermarket system.
