Designed to replace the factory sending unit with a high-flow, performance-oriented assembly, the SureFlo ensures your fuel system can keep up with the demands of a modified or high-performance LB7 — eliminating fuel starvation and keeping your CP3 fed under hard acceleration and heavy load.\u003c\/p\u003e\u003ch3\u003eWhy Upgrade to the SureFlo?\u003c\/h3\u003e\u003cp\u003eThe factory LB7 sending unit was designed for stock fuel demands.
