This procedure addresses a DEF (Diesel Exhaust Fluid) injector repair on a 1966 Chevrolet Corvette 327ci V8, which is an anachronistic request as this gasoline engine predates DEF systems by decades and has no DEF components.

Warnings

⚠️This procedure cannot be completed as specified. The 1966 Corvette 327ci V8 is a gasoline engine that does not have, and never had, a DEF (Diesel Exhaust Fluid) injection system. DEF systems were introduced for diesel emissions control starting in 2010 with EPA regulations.

ℹ️If you are diagnosing an emissions-related issue on this vehicle, the 1966 Corvette predates catalytic converters and uses a carburetor-based fuel system with mechanical or vacuum-operated emissions controls only.

Preparation

Verify the actual concern with the vehicle, as DEF systems do not exist on 1966 gasoline engines
If the concern is fuel injection related, note that the 1966 Corvette 327 uses either a Rochester Quadrajet carburetor or optional fuel injection (Rochester mechanical fuel injection), not DEF injection

Procedure

1
Identify Actual System Concern
The 1966 Corvette 327ci V8 is a carbureted gasoline engine; the optional Rochester mechanical fuel injection was discontinued after 1965, so all 1966 327 engines used a carburetor. DEF (Diesel Exhaust Fluid) injectors are components of selective catalytic reduction (SCR) systems used exclusively on diesel engines starting in 2010. This vehicle has no DEF tank, DEF injector, DEF pump, or SCR catalyst. If you are experiencing drivability issues, diagnose the carburetor or fuel injection system appropriate to this vehicle. If this work order was generated in error, consult with the service advisor to determine the actual customer concern.

Reassembly

Not applicable - this component does not exist on this vehicle

Verification

Verify the actual repair needed by consulting the customer and inspecting the vehicle's actual fuel delivery system (carburetor or mechanical fuel injection)
