It's a vent for the smog system that use to have a flexible aluminum tube that went out the hole right there in the metal inner support for the fender.
What is this and why does it blow hot air
So next to my battery and starter solenoid, there is a box on top of the classic ford coffee can blowing out hot air, with a smell of unburned hydro carbons. Wondering if This needs to be capped of or removed entirely if I am not using it. I live in SC. No inspections of vehicles.

Its the muffler for the smog system, and ive never seen it have a tube on the outboard end. On 100s of these trucks.It's a vent for the smog system that use to have a flexible aluminum tube that went out the hole right there in the metal inner support for the fender.
The plastic "coffee can" is the air inlet filter. The metal coffee can is a vacuum reservoir. The black box below the battery is the charcoal canister and it traps fuel vapors from the tank, and releases them into the intake when under load.
This is awesome. Thank you!
The AIR pump is always pumping air, either into the exhaust or out of that hose when not needed...i'm pretty sure thats how it operates.

The smog pump exhaust tube is a ribbed cardboard tube with an aluminum foil coating ircc. They usually don't last to long.
I got my 94 in 2003 with 72k miles and there was no sign of one.My 95 has it maybe it’s a 94-96 thing
