Bypass regulator expert?

Do bypass regulators bleed off fuel pressure when the engine and electric pump is off? Reason I ask is I have a heat soak restart issue and I know it will help cool fuel make it to the carb if it’s plumbed after the carb but if it doesn’t release pressure in the line at shut down i may be better off with a bypass fuel filter. thanks
Do you have a full bypass return or a deadhead return set-up?
