ECS Stage 1 E85 Fuel System for Late '03 to '13 Corvette

The ECS Stage 1 E85 fuel system keeps the factory in-tank pump and adds a secondary A-1000 pump that only runs when fuel demand rises. It is designed for mid-2003 and later C5 and C6 Corvettes. ECS reports it is stable to 800 rwhp, making it a fit for boosted cars running E85.

• Secondary A-1000 fuel pump
• Hobbs switch to activate the secondary pump
• ECS custom-machined fuel block and fittings
• Pre-made, pressure-tested high-pressure PTFE Fragola hoses

Key specifications

• Feed hoses upsized to -10AN for E85 flow
• Ties into the factory fuel lines and keeps the factory fuel rails and pressure regulator
• Proven stable to 800 rwhp and can be upgraded later
• Supplier SKU: ECS-200-001-E85
