AIR RESTRICTION GAUGE
Just for giggles I bought one of these. It arrived today, but doesn't have any instructions. The ebay ad just says "Mounts directly on air intake system."
It is a genuine Ford part, but I don't know if they actually ever used them. If so, does anyone know where Ford would have installed it? If not, where do you think would be the best place to install this?
On our Freight-shakers they're right on the air box, do you think just on the air cleaner somewhere is fine?
TIA!

It's graduated uin inches of water vacuum. 10" water is considered max. for carbureted gassers. Diesels can run a higher without losing FE. The gage has a latching feature that allows it to show the max it ever saw. High humidity can increase restriction. You also can't tell anything by looking at a filter. A dust that is close to the micron rating of the filter media can plug it without looking like it would be plugged.

They were mounted on the side of the air box on turbo trucks. At least for ATS systems, I'll assume that the stock turbos had them as well.

On my ATS system, under hard throttle and heavy load the gauge would always max out and I'd have to reset it. Intake restricted even with a new filter.
Seems like the older turbo systems had some intake restrictions and Banks was worse than ATS from what I've seen.

it mounts on the intake side of the air filter. between the filter and turbo, or on the the threaded nipple on the air cleaner lid on a n/a motor. it registers the air flow restriction. on a n/a motor you may never see it register unless the air filter is completely plugged.
if you have a turbo motor there is a good chance you will see it register something even with a clean filter.

You guys were right, under that cap was a threaded port. There was also a small 'knock out' in the port, kind of like a very small freeze plug. I broke a few small nails trying to knock it out, ended up drilling it partially out then it popped right out. Cleaned it up and got it all together.
Thanks again!

See below: pic of the guage in its factory position tapped into the side of on the 94 air box cover:
We outfit these on all our underground diesels, and they're generally all tapped into the air boxes. Helps queue maintenance in our dusty environment.

You guys that say yours didn't work are probably wrong because, if you don't run your truck off road the air filter will probably fall apart before it pulls on the resriction indicater. My lowboy truck has had the same air filter in it for 175,000 miles. On the other hand my tandem dumptruck does a lot off on site work will start to pull on it 10k to 20k miles
