the fuel line from the pump to the Y block on a 375 hp 396 with a holley dual feed is 3/8" right?
At the y block do all step down to 5/16" lines to go to the carb fittings?

can I get smaller fitting for the Holley where the fuel lines attach?


I ordered a fuel line setup from Heartbeat City and the short lines from the Y block to the carb are too small. I emailed them last night to see if maybe the kit is wrong.

thanks for the input

That's how they came from the factory.
