    Default Holley 600 cfm 080450

    Holley 080450 leaks by accelerator pump. I tried replacing the diaphragm/gasket, but it still leaks. I also checked the bowl gasket and it didn't have any tears. It was the reuseable blue kind, but it still leaks. Also made sure the fuel isn't dripping down from fuel line inlet any where. Any ideas?

    Can you show some photos please? Could be from pump diaphragm flange area, bowl or metering block gasket area, or bowl screw washer. Gary

    I sent this carb back, hopefully they refund me. I'm working on that Truck Avenger now.
