Question 87 E-150 Cooling Fan

I have a 1987 Ford E-150 Club Wagon with a 4.9 Litre EFI straight 6 and automatic transmission. Tucked deep in the right hand fender between the battery and fender is a small squirrel cage type fan that has a hose, the same size as a radiator hose, attached to it. This hose travels up the fender, over the battery, and then disappears under the air cleaner. I don't know where it goes. I've had this van over 16 years and honestly never looked. The fan seems to come on whenever the engine runs hot, but it mostly comes on after I shut the motor off, and then it only runs 2 maybe three minutes and then shuts off. What is the technical name for this fan - and what is it cooling, and why? Thanks!

It's purpose is to cool the plenum and fuel rail to help on hot restarts.
