How does the fuel injection system work on a corvette?
Carburetors and fuel-injection systems are fuel managers feeding your engine the required fuel load from idle to WOT and everything in between. Electronic fuel-injection systems precisely feed fuel while monitoring the engine’s efficiency through various sensors, providing the best possible fuel control.
Where is the fuel injector located in the fuel rail?
At the top O-ring where the fuel injector is located in the fuel rail. (Repairable – replace O-ring) The fuel Injector pintle, ball or disc seat due to damage or corrosion (Not repairable, Discard Injector) The fuel injector body at the top of the fuel injector. (Not repairable – Discard fuel Injector) Test leaking Fuel Injectors.
How does the power piston system work on a corvette?
The power piston system uses a stepped needle that restricts fuel flow through the jets, while the power valve uses a single orifice to meter fuel to the jets. Both power enrichment systems use engine vacuum to control fuel flow rate: as engine vacuum decreases relative to throttle opening so does the fuel flow restriction.
Where does the fuel injector normally leak in a car?
Where does injectors normally leak: At the top O-ring where the fuel injector is located in the fuel rail. The fuel injector body (Not repairable – discard fuel Injector) The fuel Injector pintle, ball or disc seat due to damage or corrosion (Not repairable, Discard Injector)

What kind of fuel system does a C3 Corvette have?
All others until 1981 had Rochester Quadrajet carburetors, then an archaic electronic fuel injection finished off the Shark’s C3 generation for 1982. One backfire can ruin your afternoon if your pre-1992 Holley 4150, 4160, 4165, or 4175 does not have this power valve modification done to its base plate.
How does the power enrichment system work on a corvette?
Both power enrichment systems use engine vacuum to control fuel flow rate: as engine vacuum decreases relative to throttle opening so does the fuel flow restriction. An accelerator pump is used to provide a shot of raw fuel as the throttle is opened quickly, avoiding hesitation during hard acceleration.
