Nothing less than dual Aeromotive Eliminator fuel pumps plumed with Dash -10 hose. Testing and hard earned lessons have shown that nothing less is acceptable. Aeromotive also supplies the high flow fuel filters. 
Since drift cars must sit idling and heat soaking for long periods while judges decide winners and for commercial breaks, vapor lock is always a problem even with fuel injection. A cool car helps keep the fuel cool, especially important with a high power engine that bypasses a lot of fuel during idle. 
Fuel pressure is controlled by an Aeromotive Pro Series regulator. That is not dry sump plumbing, it's how big the fuel lines have to be!
A Custom CRF radiator sits in the rear of the car with a custom shroud and two huge Flex a Lite fans. This is taken right from off road racing.
The air intake for the radiator is at the base of the rear window. This scoop helps direct air to it.
This roof spoiler helps direct air to the rear radiator scoop.
