A little sneak peek at our shop/personal car new fuel setup! This “stg 3.75” from Precision Raceworks modifies the stock bucket and drops in 2 walbro style pumps: a 535 primary and a 525 secondary, triggered by a Hobbs switch for boost-only operation. Between the 2, r hat’s enough fuel flow to support up to 1000whp! This modular bucket system from precision can start out as a single bucketed pump and gives adaptability to grow into a dual pump, or even a triple pump setup!
Best of all this retains the factory bucket and Venturi system to ensure the pumps never go dry and integrated seamlessly with the other factory fuel system components.
