Sprint Rs

Newbee question,
Can I run the engine from a slave fuel tank or does it need to be connected to the fuel pump.

 

Thanks for the help lads. Now,
2 things.
1st,
Fuel line connector that goes into the tank broke, surprise surprise.
2nd,
Datatool 3 bypassed, engine spins, pump does not prime.
When tried on my daytona power supply it works.
Relay or wiring?
Thanks.
