Air Cleaner flexible hose

The part is not being reproduced and it is stapled to the air filter snorkel. After lots of research, I have ordered a part that should fit. The measurements are almost identical to the original one (3.5 x 2.5 in). It is from Crown Automotive, part # J3231980 and is a direct replacement for some Jeep vehicles. I will try it out once it arrives and will post an updated picture.

It worked out like a charm. With a little of wiggling around the edges the hose fit perfectly and looks almost stock. If you are looking to replace the air cleaner hose, this is your option.

Great find will help lots of 73 owners for sure.
I noticed the other day that the Econoline Van, 1987 with the HO 351, has a similar hose but did not check the size.
Thanks for letting us all know the info I will order one for sure. I have 3 73.

EGR valves and ever tightening emission controls were on the way. In 1972 it started with the cars with NOX emissions (what the parts book called California cars). Those are the cars you see with the flex hose on the end of the air cleaner duct much like you see on the 73 cars. They were part of the metal air cleaner duct and valve and not available separately. As you can imagine they were not sold in great numbers once the public found what had to be purchased just to get the flex hose. The 9A624 assembly which is the hard plastic duct that brings fresh air from the front of the car to the flex hose is the same for the 302 and 351 C's. Most of the parts houses carry flex hoses that can be adapted to the air cleaner. The hose gmadrid has shown in his posting looks like a perfect candidate.

Edit....After reading David's post about the flex hose on Econoline vans, I decided to dig a little harder in the books. Ford's move to fasten the flex to the hard plastic duct (9C675) still wasn't a well received option or cost effective for Ford owners. We had a huge amount of commercial truck business in our shop and heard plenty about the cost associated with replacing the flex hose assembly. Ford finally released three different "Service" hoses.
D3OZ-9A624-B 2 5/16X3 11/16 X11
D5UZ-9A624-B 2 5/16X3 11/16X18 1/4
D7UZ-9A624-A 2 5/16X3 11/16X25 3/4
The last two numbers are van part numbers (extra length). I believe we just stocked the last one and told everyone to "Cut to fit". And you can see that the dimensions are close enough that the 3 1/2 x 2 1/2 hose gmadrid found is perfect.

Don't hold your breath waiting for a reply, the last time he was on the forum was in 2016. He already said how it worked in post #12.

And, please go to the Introduction section of the forum and introduce your car and yourself. We like pictures.

There is a popular Bronco site that carries the hose. If you Google it you can find it.

If you ain't learning, you ain't living.
