ECS Stage 1 E85 Fuel System:
The ECS Stage 1 E85 fuel System incorporates your standard intake pump, and adds a secondary A-1000 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. We have upgraded the feed hoses to support the added fuel flow demand of E85 from our standard -8AN to -10AN.
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. All ECS stage 1 fuel systems come with pre-made high pressure PTFE Fragola hoses, pressure tested and ready for install…that is an industry first and exclusive to ECS!!
The ECS Stage 1 E85 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. For earlier systems refer to ECS Stage I Fuel Systems for 1997-2003 Corvettes. ECS Fuel Systems DO NOT come with injectors.
