What does Edelbrock say to do with the vent line?

Thanks for the response, Tony…this never happen when the canister was hooked up (even when using the factory “Vacuum Pressure” cap?), but it was a QJet then. Edelbrock said to run the vent hose from their Fuel Sump Pump directly to the hardline that the canister used to run to (located down on the frame, close to the radiator). They call it a “vent”, and specifically say that a “return” is not required.
