Filter with Return: Cure for Vaporlock?

Cold air idea? Click the thread at the bottom. An open air element sucks in hot air. That could be part of the issue.
Also insulated fuel line helps.
I have a return line in the filter as stock on my ‘79 Magnum. The fuel line is 5/16 though. Maybe if you searched you would find a similar unit in 3/8? IDK…
