There is 2 PCV hoses used on the trucks...one which is the most typical from what I have seen is a hose from the PCV on the rear of the RH valve cover to the carb spacer plate which has a nipple in the rear center. This hose, according to the parts catalog is 13" long and can be cut from C3AZ6A664B which i guess to be a roll of hose even though it doesnt say so. There is another hose used on non emission reduction equipped truck(PCV I assume) this version has a hose that runs from the valve cover down the rear and out the side. This is shown in Grp 60 pg 11 top illustration of the Parts Illustration book. I have seen one of the longer hoses on ebay NOS in recent months.
I am looking for the molded one that has appeared on all truck engines that I have owned. It goes from the passenger side valve cover to the base of the carb.
Since Bill says there are none available anywhere, what value are part numbers CS???

You must be using the printed parts catalog. Take a gander at the CD.

One a the hoses is molded (C5AZ6A664C), this is the one John wants. Specs: 5/8" I.D. x 20 5/32" long.
The other hose is just 'bulk' smog hose.
Ford sez cut off the required length from a (25ft) roll of C9PZ-6A664-B.
John, I'm gonna look at some later vehicles, to see if I can find something close to the original.
Edit: A cursory glance shows that after 1972, all the various PCV hoses are cut to fit.
I know it's not correct, but...there is a 6' long 5/8" heater hose (C8OZ-18472-B) that Ford sold with a molded end.
We used to sell these, and cut off what wasn't necessary. If you want one, I can prolly find it, as it's obsolete.
John, I had the same problem as you. A PO rigged up some weird arrangement with decidedly wrong hose that of course would collapse.
I tried a couple different, not-quite-oem arrangements with different breathers, hoses, etc and finally came up with one that uses a big block Mustang hose (repro'd) and a plastic coupler to make the sizes match up. If you want a photo of mine I'll be glad to send it.
I spent 3 hours, give or take, last night/this morning looking for the pic showing it...I didnt find a thing in either truck book or car books either...only molded hose I saw was in the actual pic shown in the truck illustration book.

Take a look here kiddo for the pic of the plastic adapter that makes a straight piece of hose into a curved piece of hose.
