ECS Stage I Fuel System for Late 2003 to Current

ECS Stage 1 Fuel System:

The ECS Stage 1 fuel System incorporates your standard intake pump, and adds a secondary Bosh 044 pump that is only used when fuel demands exceed “normal” levels. The Secondary pump is activated via a hobbs switch that recognizes vacuum and boost pressure and activating the secondary pump and increasing both fuel pressure and flow.

Thanks to the custom machined ECS Fuel Block and fittings, the ECS Stage I fuel system cleanly ties into your factory fuel lines and continues to use factory fuel rails and pressure regulator.

The ECS Stage 1 fuel system has proven to be stable to 800 rwhp and is easily upgraded should your HP grow at a later date.

This ECS Stage I Fuel System is designed for mid 2003 and later C5 & C6 Corvettes with the fuel pump and lines coming out of the top of the tank. For earlier systems refer to ECS Stage I Fuel Systems for 1997-2003 Corvettes. ECS Fuel Systems DO NOT come with injectors.
