I am getting ready to install a Holley "Red" electric pump. I am having fuel starvation issues with just the mechanical pump. My question is, can I wire the pump off of the wiring that goes to the tank? Can I hook the pump to the tan wire, or is that too much load for the wire? I would prefer to not have to wire up a switched relay to the battery.

Thanks.

 

I would run the Holley pump from the grey wire just as you suggested. That way you're already fused (20 A) and it is switched by the oil pressure switch off the engine.

If your ride is factory injected the ECM will prime the pump for a few seconds before cranking too. It's all good.
