I just bought this item for use in my 1926 T coupe here in Florida. Every little bit helps to beat the heat. Does anyone have one of these in their T? Are they efficient? What is the best way to hook them up? I assume running a vacuum hose from a fitting installed on the intake manifold is the best vacuum source. Since a vapor of gasoline passes through the intake, does this introduce gasoline fumes into the Trico vacuum powered accessories whenever the accessory is not being used? Thank you. Jim Patrick.

Just the opposite. The fan operation runs clean air into the manifold. For this reason, the vacuum tap-off must be somewhat centered and low enough on the intake manifold to balance the air between the front and rear pairs of cylinders. I would imagine that you should adjust the fuel mixture about 1/8 to 1/4 richer to compensate for the added air when running the fan. The same is true when using a vacuum windshield wiper, however they pull a little less air and have slightly less affect on the engines running.
I have had several cars (including my T boat-tail) that use vacuum tank fuel pumps. You can tell when the tank shifts pumping cycles by the way the engine runs, but it only lasts for a second or two with them.
Neat accessory.
Drive carefully, and enjoy, W2
