The Motorcraft FG-15, C5AZ-9155-B, fuel filter looks exactly like the original one on Perkin's carburetor. Except for the markings, it has the raised circle on the hex installation nut but I can't see what the hose fitting end looks like. It's made in China.

Be careful!

Different Autolite and Motorcraft fuel filters actually have different threads...some coarse, some fine, and even different sizes!  You can easily cross thread the wrong fuel filter and have a big mess on your hands as this has been done by accident thousands of times.  Make sure that you double-check the EXACT application and slowly check the threads to make sure that you have the correct ones.

If you look at the Perkins picture above, What you are looking at is a Ford "Rotunda" assembly line fuel filter.  Rotunda fuel filters were also sold over the counter at Ford Dealers as well just like Autolite and later what became Motorcraft. Both were owned by Ford, but Rotunda was Specifically a Ford/Lincoln/Mercury parts supplier only..sort of an internal Ford Parts Supplier.  Autolite and Motorcraft were different than Rotunda in that they made parts for other vehicles as well such as GM and Mopar, and not just Ford products.

I just measured the threads on a FG-15 filter, 1/2-20. It will thread onto a 65 carburetor (C5ZF E) fuel inlet but the gasket will "seat" LOOSE between the carburetor and filter, as in leaks. The filter has the inward taper to seat on the outward taper of the carburetor inlet port and whether that is enough to seal, I don't know. The filter is for my 66 cars.

the image provide by RRENZ matches what I have on my unrestored 66 coupe, again a late built 66 Dearborn example

haven't seen any for sale in some time and the Autolite variation some sellers have been chasing north of $75usd for.

"would there be a difference between a 66 ford supplied filter and a shelby supplied?"

Yes.

A standard Mustang V8 would have an Autolite 2100 or Autolite 4100 Carb using a Ford Rotunda or Autolite Fuel Filter.

A '65-'66 Shelby GT-350 would normally have a Holley 715CFM carb with a different type of fuel filter for the carb.  I'm sure that Mr. Speegle can eleborate better than I on this..when he chimes in..

You are mis informed. Shelby used the same filter but also had a brass adapter to complete the installation.

Chiming in  :)  As Bob mentioned Shelby didn't use any special or different filter just an adapter to make the Mustang one fit the different (Holley) carb

Jeff or Bob,
Do either of you have a picture of this adapter that Shelby used?  I'm trying to locate one for purchase.  Is there a supplier that you know of who sells them?

Brant at Virginia Mustang or Jim at Shelby Parts and Restoration would be two of the places that should have them

Both members here  :)

Question really is off thread considering its placement ;)

spoke to Jim, he is checking if he has the 1" adapter that Shelby would have used when switching from the autolite to holley carb. 

Thanks for the lead.

Tony : Not quite correct. While Ford may have been the only major car manufacturer using Rotunda parts on the Assembly line, the Rotunda Service Parts line was just the opposite. Rotunda made some parts just for Fords going back to the late 50's, but in 1964 decided to push their brand to the full car market, touting the Rotunda line as having "Universal Applications". This can especially be seen in the Rotunda Accessories, which while they included instructions, templates, etc. for Ford bars, they also included them for "Universal Applications". The sole "Rotunda Only" parts catalog produced was in 1964, and the inset noted that it was for all car makes (picture attached). They did have separate specific parts catalogs, like the 1967 Rotunda Muffler catalog (picture attached), which again noted that it was for "all makes". During Rotunda's "heydays" of mid 60's to early 70's, FoMoCo parts, just for the Ford Family of cars, were still being produced. As a matter of fact, going back to the 50's, I can't think of any FoMoCo parts, other than maintenance products, that were "touted " to be of "Universal Application" (not to say that some couldn't have been used as such).

Just thought that I'd clarify this a bit so that someone reading your Post doesn't think that "Rotunda Parts" were only "Ford Parts". They were actually much like the Autolite parts you mentioned.
