Alternative Ventilation
Has anyone perfected a simple interior ventilation system once the hvac is blanked off and deleted in an early 914?

My goal is to have a two-sided control total mechanical system to shove some fresh air into the cabin when the windows are up / one side or the other or both / not to the windshield but to the lower cabin only.

In SoCal, we have no humidity, no rain, no inclement weather, not one single bug, no latent dust (unless behind a 6…, and no particulate allergens or pollen, so I am thinking that the system will be an add-on to my tow bar hitch receiver tubes subtly located thru the front bumper and in to the front trunk bay… but…. from there, things get difficult due to this big bulbous thing called a fuel tank…..

I know from many removals and insertions of the tank that there is no room for two flexible tubes to make their way thru the tank cavity unless we agree to go electric.
So, maybe someone has another route for two individually mechanically controlled vent tubes to the front cabin.

Of course, the Germans used the cowl vent to drain rain and to power up ventilation to the cabin and windshield. I am looking for a simple alternative.. Any suggestions are appreciated.
