Fresh Air Intake (hose)

[billrigsby]

 

I picked up a fresh air intake setup the other day, in very good shape.

 

Grill end;

 

 

 

Firewall end, the flapper still has the original sealing felt on it.

   

 

  

 

Wonder if anyone knows what the original 4" hose looks like or a source?

[wallytoo]

the hose is fabric wrapped around wire (like a slinky, sort of).

I sourced a new 4" duct hose at Napa. I like it better than the original as it's more flexible and lighter. Use spring clips for a dryer duct - you can get at the hardware store. 

[dcotant]

Can you share the part # for the hose?

[John-T-53]

I don't have one, I think I just asked for duct hose at the counter. 

 

The Jegs link by B1B Keven above looks like a winner too.

 

Here's something on Rock auto:

I don't know of a "identical" type of hose out there, most now are a coil wire wrapped with a plastic convolute.  The originals were more of a fabric and "flatter" and you don't see the wire proud on the hose.

has anyone tried to replace the felt on the flapper?  Mine is only 1/2 way around

[gramps1951]

I wonder why they thought that they needed a fresh air intake when they all had the pop up vent in front of the windshield. I must be missing something.

This is to force outside air through the heater in colder weather vs the cowl vent for cooling during hotter weather

Fresh air can help defog the windows rather than recirculating the moist air within the cab.

yes, I took mine down to components and rebuilt the whole thing.

[billrigsby]

Started to clean up the fresh air intake today, on the grill end,

my guess is there is a screen to curtail the intake of bugs.

 

Probably using these clips?

Does any one know the correct grid size and proper attachment?

Still got a bit to go on this piece.

 

Also got the flapper dismantled to de-rust and paint.

Yep a square pattern screen about 1/4" squares.  PM if you need and rivets or anything.

[billrigsby]

Well, just when you thought you were off to the races, 

Found out I am missing a part, will search, or re-create.....

 

 

Once again, wondering if anyone has dimensions?  ?

Thanks, I was thinking about that size, of course I have whole rolls of 1/2" and 1", time to do some digging in the scrap boxes

as far as rivets go, Dad left me well supplied with a few lifetime's supply of them from UAL.

I like the looks of that, pretty close match.
