Topic: Parts ID - vacuum fitting applications

[tim_morrison82]

Hi,

Thanks for your help guys. I need another hand. Do you knowledgeable people know what these vacuum fittings are off?

Bottom two are 390 - 427 - 428 from 1966 - 1970. The angled 5/8" nipple would connect to one end of the PCV U - tube.

Top one could have been used on many car lines with many different engines in the same period depending on options. For a big block car it would screw into one of the other two again depending on options.

You can see each of these items at Mansfield Mustang's web site.

I found only the fitting in the lower picture on the left hand side as Mansfield Mustang stock number FIT-103. The other two I could not match pictures. It was listed as 69 428CJ/428SCJ engines.

The one on the left would be typical of a non-power brake car and the one hose nipple would be used for the ram air flapper on an R-code.  Probably other applications for this fitting as well but this is the one I am familiar with.

The one with the larger hose port I tracked down to something along the lines of C8AZ-9425-B or C8AZ-9424-A.  I pulled one off a 1968 Torino GT 390.  Refer to the attached pics

The upper part is a 9A474 - not sure what prefix or suffix. Mansfield shows a C8OZ 9A474-B in one photo, those have two nipples while the one in the OP's first post has three so it's a little different application but same base number.

The lower right one is a little odd but would only fit an FE in the 1966 - 70 model year range. The ones with good value are the ones being sold by Bill.
